This is the main Image Creator developer's guide. For a more simplistic, step-by-step document, go to: Image Creation For Beginners.
The tool used to create MeeGo images is called "MIC2" (to distinguish from obsolete MIC - Moblin Image Creator). MIC is composed of a series of tools to create images, convert images, and do some development work on MeeGo. MIC2 is based primarily on Fedora livecd-tools and appliance-tools.
With MIC2 tools, users can create different types of images for different purposes, including live CD images, live USB images, raw images for KVM, VMDK images for Vmware, vdi images for VirtualBox, loop images for IVI platforms, NAND images for Moorestown platforms, ubi images for N900, fs image for MeeGo developers. Also, users can use MIC2 tools to manipulate images, like transforming an image from a virtual machine to a live image, and providing a chroot environment based on an existing live image. With these features, developers can do development work on a host virtual machine running MeeGo or a Meego chroot environment, and transfer the resulting new live image to a target device for final debug/verification.
This document discusses only features, usage guide, and known issues.
MIC2 offers these major tools:
The following support is provided:
To use MIC2, your host machine (that will run mic2) must have Intel* Atom* or Intel* Core* 2 CPU (support for SSSE3), this is a hard requirement (ARM image is exceptional), the following packages must be available on your system. (Most of the packages are installed by default, depending on the distribution.):
You should load these modules, as well, if they're not loaded automatically by the kernel:
(Use lsmod to list modules.)
Specific packages for Fedora:
Specific packages for Ubuntu 8.10:
sudo apt-get install yum rpm kpartx parted syslinux isomd5sum kvm zlib1g-dev squashfs-tools python2.6-dev qemu-arm-static python-urlgrabber
We currently build MIC2 binary rpms/debs for many popular Linux distributions, including Fedora 11, Fedora 12, Ubuntu 9.10, Ubuntu 10.04, OpenSUSE 11.1, OpenSUSE 11.2, and Debian 5.0. Please go to http://repo.meego.com/tools/repos/ to get a repository URL corresponding to your Linux distribution, then add it into your repo or package source for installation and update later. If your distribution isn't in the support list, please install MIC2 from git source.
1. Add MIC2 repo as user root:
# cat <<REPO > /etc/yum.repos.d/meego-tools.repo [meego-tools] name=MeeGo Tools for Fedora baseurl=http://repo.meego.com/MeeGo/tools/repos/fedora/\$releasever enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-meego REPO
2. Add gpg key as user root:
# gpg2 --keyserver subkeys.pgp.net --recv 0BC7BEC479FC1F8A # gpg2 --export --armor 0BC7BEC479FC1F8A > /etc/pki/rpm-gpg/RPM-GPG-KEY-meego
3. Install mic2 as user root:
# yum install mic2
if you get asked to import the key do so:
warning: rpmts_HdrFromFdno: Header V3 DSA/SHA1 Signature, key ID 79fc1f8a: NOKEY meego-fedora/gpgkey | 3.3 kB 00:00 ... Importing GPG key 0x79FC1F8A: Userid: "Moblin Build (Moblin Build User) <build@moblin.org>" From : /etc/pki/rpm-gpg/RPM-GPG-KEY-meego Is this ok [y/N]: y
You can use the below command to get the latest mic2 package.
# yum update mic2
1. Add package source
For Ubuntu 9.10, add the below line to /etc/apt/sources.list
deb http://repo.meego.com/MeeGo/tools/repos/ubuntu/9.10/ /
For Ubuntu 10.04, add the below line to /etc/apt/sources.list
deb http://repo.meego.com/MeeGo/tools/repos/ubuntu/10.04/ /
For Ubuntu 10.10, add the below line to /etc/apt/sources.list
deb http://repo.meego.com/MeeGo/tools/repos/ubuntu/10.10/ /
For Debian 5.0, add the below line to /etc/apt/sources.list
deb http://repo.meego.com/MeeGo/tools/repos/debian/5.0/ /
mic2 is also available in Debian Testing, which will become Debian 6.0.
2. sudo apt-get update
You should see the following error: W: GPG error: http://repo.meego.com Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 0BC7BEC479FC1F8A
To add the repository public key use the following command:
Note: Often the port used by gpg is blocked in companies, so gpg will time out. You can install it manually; this example is for Ubuntu 10.04:
Open System->Administrator->Software Sources. Under the Authentication tab, import the key.
Now redo sudo apt-get update
3. sudo apt-get install mic2
1. Add repos
For OpenSUSE 11.1:
sudo zypper addrepo http://repo.meego.com/MeeGo/tools/repos/opensuse/11.1/ meego-tools
For OpenSUSE 11.2:
sudo zypper addrepo http://repo.meego.com/MeeGo/tools/repos/opensuse/11.2/ meego-tools
For OpenSUSE 11.3:
sudo zypper addrepo http://repo.meego.com/MeeGo/tools/repos/opensuse/11.3/ meego-tools
For OpenSUSE 11.4:
sudo zypper addrepo http://repo.meego.com/MeeGo/tools/repos/opensuse/11.4/ meego-tools
2. sudo zypper install mic2
sudo zypper update mic2
You can get the latest stable release of MIC2 from the tag section in http://meego.gitorious.org/meego-developer-tools/image-creator. Click on the "Source tree" link on the top of the screen. There will be a list of tags on the right hand side.
You should follow the below steps to install it:
git clone git://gitorious.org/meego-developer-tools/image-creator.git cd image-creator git checkout 0.17 #check Gitorious for the most recent tag make sudo make install
Note: MIC2 GIT tree has latest-and-greatest source, so stability is not guaranteed. If you run into errors, please use a 'Stable Release' instead before filing a bug.
You need to follow the below steps to git clone MIC2:
git clone git://gitorious.org/meego-developer-tools/image-creator.git
Build and install:
cd image-creator make clean make sudo make install
You should add the repo for mic2 then run
sudo ./tools/mic-check-alldeps
to check/install all the depended packages, otherwise mic2 can't work normally.
If you need to use proxy to access Internet, you must set proxy for mic2 correctly. Generally, you should export these environment variables:
$ export http_proxy="http://proxy.yourcompany.com:8888" $ export https_proxy="http://proxy.yourcompany.com:8888" $ export no_proxy="127.0.0.0/8, .yourcompany.com"
If you use sudo to run mic2, you also need to add these into /etc/sudoers in order that they still are valid after sudo.
$ sudo visudo Add: Defaults env_keep += " no_proxy http_proxy https_proxy"
so sudo will adhere to the no_proxy and proxy settings.
You also can set proxy in /etc/mic2/mic2.conf or in ~/.mic2.conf by adding the below two lines:
proxy=http://proxy.yourcompany.com:8888/ no_proxy=localhost,127.0.0.0/8,.yourcompany.com
Of course, you need to change proxy.yourcompany.com:8888 and .yourcompany.com according to your network.
From mic2 0.23.0 on, mic2 enabled zypp backend, it uses /etc/sysconfig/proxy to get proxy settings, so you also need to create this file (it is a system file in OpenSUSE, so for openSUSE, you just set correct values inside of it) if you need to use proxy to access internet. Here is a sample:
#### /etc/sysconfig/proxy sample #### ## Path: Network/Proxy ## Description: ## Type: yesno ## Default: no ## Config: kde,profiles # # Enable a generation of the proxy settings to the profile. # This setting allows to turn the proxy on and off while # preserving the particular proxy setup. # PROXY_ENABLED="yes" ## Type: string ## Default: "" # # Some programs (e.g. lynx, arena and wget) support proxies, if set in # the environment. SuSEconfig can add these environment variables to # /etc/SuSEconfig/* (sourced by /etc/profile etc.) - # See http://portal.suse.com/sdb/en/1998/01/lynx_proxy.html for more details. # Example: HTTP_PROXY="http://proxy.provider.de:3128/" HTTP_PROXY="http://proxy.yourcompany.com:8888/" ## Type: string ## Default: "" # # Some programs (e.g. lynx, arena and wget) support proxies, if set in # the environment. SuSEconfig can add these environment variables to # /etc/SuSEconfig/* (sourced by /etc/profile etc.) - # this setting is for https connections HTTPS_PROXY="http://proxy.yourcompany.com:8888/" ## Type: string ## Default: "" # # Example: FTP_PROXY="http://proxy.provider.de:3128/" # FTP_PROXY="http://proxy.yourcompany.com:8888/" ## Type: string ## Default: "" # # Example: GOPHER_PROXY="http://proxy.provider.de:3128/" # GOPHER_PROXY="" ## Type: string(localhost) ## Default: localhost # # Example: NO_PROXY="www.me.de, do.main, localhost" # NO_PROXY="localhost, 127.0.0.1, .yourcompany.com" #### /etc/sysconfig/proxy sample ####
You need to change proxy.yourcompany.com:8888 and .yourcompany.com according to your network. By default, zypp will be used, but you can use option --pkgmgr=yum to force mic2 to use yum, you can do so if you find zypp can't work for you, but remember to file a bug on http://bugs.meego.com/enter_bug.cgi?product=Development%20Tools&component=MIC%20(Image%20Creator) if you find any issue related to zypp.
An option --proxy for repo command in kickstart file also can set proxy, you can specify it as follows:
repo --name=meego --baseurl=http://repo.meego.com/trunk/repo/ia32/os/ --proxy=http://proxyhost:proxyport/
You also need to add two more options to repo if your proxy needs user authentication:
repo --name=meego --baseurl=http://repo.meego.com/trunk/repo/ia32/os/ --proxy=http://proxyhost:proxyport/ --proxyuser=proxyusername --proxypaswd=proxyuserpassword
Configuration of images is based on kickstart, the format used for unattended installation in Fedora and Redhat.
Super user privileges are needed. The tool is more or less self-documented, use the --help option to see options.
sudo mic-image-creator --help
KickStart (.ks) configuration files are passed to MIC2 to create tailored images. KickStart files specify what repos to pull from, what packages to include, what post-scripts to run and what type of images to create.
To obtain the official Meego .ks files, go here: http://wiki.meego.com/Image_Creation#Official_Meego_.ks_files
Create ARMv7 Images
When creating images for ARMv7 hardware, pass --arch=armv7l to mic-image-creator commands.
Create Livecd Image
sudo mic-image-creator --config=default.ks --format=livecd --cache=mycache
This tells image-creator to use the kickstart file default.ks to obtain info about which packages to download and include in the image, and --cache is the directory on your local machine which will host a cache of these packages. The cache is very useful if you are remote to the server and reduces the amount of downloaded packages next time you create an image. Next time the command is run, this cache will simply be 'updated' if there are changes, rather than re-downloading from the repositories again.
The output of this command will be a file named meego-1.0-default-XX.iso created. This ISO image is a hybrid image and can be either written to a disk device or burned onto a cd.
To burn it onto a USB stick, just run the following command, assuming the USB stick is /dev/sdb in your system:
sudo mic-image-writer meego-1.0-default-XX.iso
Create Moorestown NAND Image
sudo mic-image-creator --config=default.ks --format=mrstnand remove the first 512 bytes from the image to remove the partition information. sudo dd bs=512 skip=1 if=meego-1.0-default-XX-sda.bin of= meego-1.0-default-XX-nand.img
Create Liveusb Image
sudo mic-image-creator --config=default.ks --format=liveusb --cache=mycache
A file named meego-1.0-default-XX.usbimg will be created. To burn it onto a USB stick, run the following command, assuming the USB stick is /dev/sdb in your system:
sudo mic-image-writer meego-1.0-default-XX.usbimg
This image has a FAT file system and can be mounted easily on Windows and other OSes.
Create Liveusb Image Interactively
sudo mic-image-creator --config=default.ks --format=liveusb --interactive --cache=mycache
It directly creates a MeeGo live usb stick.
Liveusb image can be created in two different ways, interactive and non-interactive (default). When running MIC2 in a non-interactive mode, MIC2 creates a USB images file that can be copied directly into a USB stick. The non-interactive mode can be used for daily build or automated testing. The interactive mode will write the images onto a USB disk, it will detect if a USB stick is available and detects and verifies a partition is available. If two or more USB devices are present, you will be asked to select the target device. This way the contents of the existing USB stick won't be destroyed unless no appropriate partition is found, end user should use it to create the live USB.
Create Loop Image
This is the simplest image format available. Such images can be loop mounted and chrooted into, for example, to build applications or for debugging purposes.
sudo mic-image-creator --config=default.ks --format=loop --cache=mycache
A file named meego-1.0-default-XX.img is created. You can use below to mount it and chroot into it.
sudo mount -o loop meego-1.0-default-XX.img /mnt sudo chroot /mnt su -
Create KVM Image
Can be used with QEMU or other VMM applications to launch MeeGo as a virtualized instance.
sudo mic-image-creator --config=default.ks --format=raw --cache=mycache
A file named meego-1.0-default-XX folder with a meego-1.0-default-XX-sda.raw image is created. For optimal results, use this feature in a machine with VT support and enable it in the BIOS.
If you use Fedora or openSUSE, run the following command to launch the image into MeeGo KVM virtual machine:
sudo qemu-kvm -m 512 -boot c -hda meego-1.0-default-XX-sda.raw -std-vga
If you use Ubuntu, run the following command launch image:
sudo kvm -m 512 -boot c -hda meego-1.0-default-XX-sda.raw
Create VMDK Image
VMDK images can be loaded into Vmware or Vmware player. MIC2 also generates a VMX file that has image configuration and can be used to launch the image in Vmware by just clicking the file. If you have vmplayer, it should open automatically.
sudo mic-image-creator --config=default.ks --format=vmdk --cache=mycache
A file named meego-1.0-default-XX folder with both meego-1.0-default-XX-sda.vmdk image and meego-1.0-default-XX-sda.vmx is created. Just run vmware or vmware player, and select the generated vmx file.
KickStart (.ks) configuration files are passed to MIC2 to create tailored images. KickStart files specify what repos to pull from, what packages to include, what post-scripts to run and what type of images to create.
For more details about the kickstart format, see http://fedoraproject.org/wiki/Anaconda/Kickstart.
Note that not all KickStart directives and options are supported for creating Meego images. MIC2 also adds some specific directives and options. More explained below.
The official Meego .ks files are here:
You can download and use them as a base for the Meego images you create. Modify these .ks files as you wish to create tailored images.
Developers may want to modify the .ks files to create their own custom images. Here are the main options and sections within the .ks file.
You can also find in-depth .ks option information here: http://fedoraproject.org/wiki/Anaconda/Kickstart#Chapter_2._Kickstart_Options
Partition, Setup and Bootloader options
Example
lang en_US.UTF-8 keyboard us timezone --utc America/New_York auth --useshadow --enablemd5 part / --size 1500 --ondisk sda --fstype=ext3 rootpw meego xconfig --startxonboot bootloader --timeout=0 --append="quiet" desktop --autologinuser=meego --defaultdesktop=xfce user --name meego --groups audio,video --password meego
These are mostly self-explanatory and set up important things such as partition size, filesystem type, kernel paramters, etc. You can change these depending on what your needs are.
Repos
This is where you can specify the yum repositories that you want MIC2 to search and pull your packages from which to make up your image. You can add official Meego repos, other remote repos, or your own local repos on your dev machine.
Example
# This is a comment # My first repo repo --name=trunk --baseurl=http://mytrunk.myrepo.com # My second repo #repo --name=<repo-name-2> --baseurl=< url | local-repo-dir >
NOTE: --name of the repo can be any unique alphanumeric name you give your repo, it can be anything. Just make sure you don't use the same name twice for any of the listed repos, remember they have to be unique.
To create a repo you can point to on your local developer machine, you can run the following command:
createrepo -d <local-dir>
Where 'local-dir' is a local directory on your machine that contains the rpms you want include in your local directory.
Adding Packages and Package Groups
Example
%packages # Example adding pkg groups @Core @X for Netbooks @Base @Development Tools @<my-PkgGroup1> @<my-PkgGroup2> # Example adding individual pkgs kernel-netbook xorg-x11-server-Xorg-setuid carrick xorg-x11-drv-evtouch <my-pkg-1> <my-pkg-2> %end
This specifies exactly what packages will be included in your image. Package groups can be specified with a "@" preceding it, as you can see from the examples above. Package groups are defined in the 'repodata' section of a repo, under a 'comps*.xml' file. Defined therein are package group names, and what packages are included in each package group. The Meego package groups are standard, and cannot be changed. You can, however, define your own package groups in your own non-Meego repos, if you are using those.
Please see here for more info on defining package groups in repositories: TO-DO-LINK
You can also add individual package names to be included in the image as you can see from the second part in the above example.
Important Note about how MIC2 picks a package when different versions are available
A common problem is that, let's say, a packageA has more than one version residing in a repo(s) that your .ks is pointing to.
How will the MIC2 know which one to pick?
Example
There exists in the repo(s) these different versions of PackageA:
PackageA-1.0
PackageA-2.0
PackageA-3.0
MIC2 will pick the PackageA with the highest version number (PackageA-3.0 in this case).
There is one way to get around that, and that is to set the 'Epoch' version within a package .spec file.
Example (works in both .spec and .yaml file) Name: <name> Summary: <summary> Epoch: 1 Version: <version>
MIC2 will first look to compare the 'Epoch' version of the packages. All Meego official packages do not include an 'Epoch' version, so if you set the 'Epoch' number within your .spec file to any positive integer, no matter if your package version is smaller, MIC2 will choose your package.
So back to our example.
Example
PackageA-1.0 (Epoch not set)
PackageA-2.0 (Epoch = 1)
PackageA-3.0 (Epoch not set)
MIC2 will choose PackageA-2.0 in this case. And it follow that:
Example
PackageA-1.0 (Epoch=100)
PackageA-2.0 (Epoch = 1)
PackageA-3.0 (Epoch not set)
MIC2 will choose PackageA-1.0.
Remember that Meego packages will not have 'Epoch' set, so chances are that if you set 'Epoch' in your own package to any positive integer, it will be the one MIC2 chooses to pull down and include in an image.
Removing Packages
If you would like to make sure that a pkg is _not_ included, you can specify that with a '-' preceding the package name.
Example
%packages # Example pkg groups @Core # Example adding individual pkgs kernel-netbook # Example removing individual pkgs -carrick -package-xyz %end
with the above example, packages 'carrick' and 'package-xyz' will _not_ be included in the image.
Note: all packages that depend on the package you want to remove should also be removed, or else MIC2 will ignore your request to remove that package from an image. For example, if 'carrick' depends on 'package-xyz', and you specified only to remove 'package-xyz', and keep carrick, MIC2 will ignore the request to remove package-xyz (since carrick depends on it), and it includes both of these pgks in the image.
Post scripts
You can also specify post-scripts to be run after the image is installed.
Example
%post
# Example - saving some space
rm -f /boot/initrd*
rm -f /core*
# Example - Install working xorg.conf
if [ -f /usr/share/my.conf ]; then
cp /usr/share/my.conf /etc/X11/xorg.conf
fi
# Example - Tell alsa the correct audio card to use for your platform
echo -e "options snd-hda-intel index=0\noptions snd-timbi2s index=1" > /etc/modp
robe.d/alsa.conf
%end
MIC2 options can be specified in a global configuration file (/etc/mic2/mic2.conf) and local configuration file ($HOME/.mic2.conf) where you can specify
that you normally would have to re-type in your command-line.
The two configuration files have the same format, /etc/mic2/mic2.conf is global, no matter whoever is running MIC2, this configuration file will be read first, $HOME/.mic2.conf is just valid for current user, every user can have their own settings. The final configuration is a combination of two configuration files, options in $HOME/.mic2.conf will override those from /etc/mic2/mic2.conf. Options from command line have the highest priority. If an option is specified on the command line, the same option in both configuration files, global and local will be ignored.
Below is an example you can cut-and-paste, and reuse for your needs:
[main] cachedir=/home/user1/mycache tmpdir=/home/user1/mystorage/tmp outdir=/home/user1/mystorage proxy=http://my.proxy.com:911/ no_proxy=localhost,127.0.0.0/8,.mysite.com,172.16.0.0/16
cachedir = directory where the cached repo(s) will reside. With this variable set, you do not need to pass the --cache flag in the command-line.
tmpdir = temporary directory used by MIC2 when creating images. With this variable set, you do not need to pass the --tmpdir flag in the command-line.
outdir = where your images will reside once they are created. With this variable set, you do not need to pass the --outdir flag in the command-line.
proxy = specify your proxy if you're behind a behind a firewall.
no_proxy = specify what domains should not sure the proxy setting.
image_format = specify image format.
default_ks = specify a default kickstart file, there are several kickstart files provided in repository http://repo.meego.com/MeeGo/devel/trunk/repo/ia32/os/
Note: When specifying proxy and no_proxy, you do not need to use the --proxy flag in your .ks files when referring to repos.
In configuration files, you also can specify one or multiple repositories, for example:
[trunk] name=trunk baseurl=http://repo.meego.com/MeeGo/devel/trunk/repo/ia32/os/ enabled=1
Once there is this repository info in your configuration files, and both image_format and default_ks are set, you can just run "sudo mic-image-creator" to create a image, there isn't any extra argument needed.
MIC2 highly depends on yum and librpm, but different Linux distributions used diffrent yum and librpm versions, so MIC2 has some compatibility issues on OpenSUSE, Ubuntu and Debian, bootstrap is just for fixing these compatibility issues.
bootstrap is a minimal MeeGo file system, MIC2 can run very smoothly on it using chroot mode. You can use the below command to create a bootstrap:
sudo mic-create-bootstrap -n trunk -k /your/repo/cache/path -r http://repo.meego.com/MeeGo/builds/trunk/latest/repos/oss/ia32/packages/ -o /your/final/bootstrap
NOTE: The repo-url specific for your needs may differ
-n is used to specify repository name, if you have its cache before, it can reduce runtime dramatically to use it with -k option, -k is used to specify your repository cache dir, -r is used to specify MeeGo main repository.
Once you created your bootstrap, you can use this bootstrap to run MIC2 as follows
sudo mic-image-creator --bootstrap=/your/final/bootstrap --format=livecd --config=default.ks --cache=/your/repo/cache/path
Alternatively, you can create and use bootstrap in one mic-image-creator run as follows
sudo mic-image-creator --build-bootstrap --bootstrap=/your/final/bootstrap --format=livecd --config=default.ks --cache=/your/repo/cache/path
mic-image-writer writes a Meego image to a USB disk as an alternative to dd.
mic-image-writer can run in both console mode and GUI mode. It can decide which mode to run, according to current system environment. You can also use a given option to force it to run in some other mode. Run 'mic-image-writer --help' to get usage information:
Usage: mic-image-writer [options] [image file] Options: -h, --help Show this help message and exit -c, --console Run in console mode -g, --gui Run in GUI mod
Here is a run example in console mode:
$ sudo mic-image-writer meego-xxx.img
Available usb disk:
[1] /dev/sdc: SanDisk USB Flash Drive
[2] /dev/sdb: SanDisk U3 Cruzer Micro
Please choice [1..2] ? 2
Source: /myhome/meego-xxx.img
Target: /dev/sdb
Image size: 559 MB

8944+0 records out
586153984 bytes (586 MB) copied, 63.0486 s, 9.3 MB/s
mic-image-writer can estimate how long it will take to write the given image to your USB disk and reports current writing progress. It automatically unmounts your USB disk, if it is mounted. If your USB can't be unmounted, it will terminate.
If you love UI mode, you can run it in X enviroment. The command with the added -g flag:
sudo mic-image-writer -g meego-xxx.img
Image name is optional.
It's very easy to use:
sudo mic-image-convertor --source-image=InputImage --target-format=Targegformat sudo mic-image-convertor -I InputImage -T Targegformat
For example, to translate a KVM raw image to livecd image, just type:
sudo mic-image-convertor --source-image=meego-core-200902200545/meego-core-200902200545-sda.raw --target-format=livecd
A new livecd image of meego-converted-from-raw-200902201804.iso is generated. The tool can detect the type of input image, either raw or vmdk.
This tool is very useful. For example, the developer can launch a virtual machine running MeeGo v2 and make whatever changes on the virtual system like yum install/remove a package, scp a source tarball to VM and build and try, and etc. Then with a simple "sync" or shutdown of VM, the VM image now contains his changes. With this tool, the VM image can be transformed to a live image and burned to a USB flash disk. Now developers can have final verifications in a target device, with changes in the live system.
There are two major usage models for mic-chroot for developers.
chroot directly into the image to use it as a development environment, then optionally create a new image based off of your changes
sudo mic-chroot -c livecd meego-core-200903131337.iso
The above command would present a chroot, using the livecd image, to developers with some bind mounts like /proc /sys /dev/pts and /parentroot. With those bind mounts, developers now can easily exchange files in chroot env with host /parentroot, and conduct yum install, yum remove and any other network related operations. After done and typing "exit", a new live ISO image is created from the chroot env with the changes developers made.
Unpack and modify the image's filesystem (which you can save), and create a new image based off of your changes
Sometimes developers want to keep the chroot env so that they can do multiple changes in that root file system at different times. So they want to execute following:
sudo mic-chroot -s my-chroot-fs --unpack-only meego-core-200903131337.iso --bind-mounts=/proc:/proc;/:/parentroot;/sys:/sys;/dev/pts:/dev/pts
The above command creates a folder called 'my-chroot-fs' in the current directory, using the chroot environment from the livecd image. Of course if one forgets to add the --bind-mounts options, you'll need to manually do the bind mounting yourself. Don't forget copying /etc/reslov.conf into my-chroot-fs if you need to use DNS. Should you wish to create an image from the chroot, just execute following to create a livecd image
sudo mic-chroot -c livecd --convert-only my-chroot-fs/
You need to copy a kickstart file into /root/mic2-ks.cfg which is used for automated installation of the image. To activate autoinstall mode, boot with autoinst on the command line or add --menus=autoinst to the bootloader directive in the kickstart file you use to create the image.

You can file a bug on http://bugzilla.meego.com/enter_bug.cgi?product=Development%20Tools (Note: you should select MIC for component) if you run into any MIC2-related issue, bugzilla can track your issue faster and more efficiently.
libgcc_s.so.1 must be installed for pthread_cancel to work" "Error: failed to create image : '/sbin/mksquashfs /var/tmp/imgcreate-FKCSsk/iso-u8xCPh/LiveOS/osmin /var/tmp/imgcreate-FKCSsk/iso-u8xCPh/LiveOS/osmin.img' exited with error (-6)
This error occurs when MIC2 is unable to find the proper version of libgcc. This usually happens on x86_64 systems - MIC2 is looking for the 32 bit version of libgcc, but only the 64 bit version is installed. Installing the 32 bit version of libgcc should resolve this.

This error can also be an issue with the syslinux package. Try updating to the latest version for your distro.

This is a race condition with device-mapper in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=506644. Usually rerunning the MIC2 command will resolve this.

Some people are using python they built themselves, so some python modules aren't under their python library path. For such error, only one way is not to use your own python but to use python your system installed.
On debian-based distros, we used pycentral to package mic2, but mic2 source installtion used distutils, so two kinds of installation have different installation path, if they exist there at the same time, it will result in some unpredictable errors to run mic2. In order to run it correctly, you can only keep just one installation, source or binary.
Remove binary installation
sudo apt-get remove mic2
Remove source installation

Note: You must replace <PYTHONLIBPATH> with the above python lib path
If program jams after mkfs.vfat, it might be due missing vol_id program. vol_id is replaced with blkid in new ubuntu versions. Try run /lib/udev/vol_id, if it's missing you have troubles.

This error occues when trying to build ARM images without passing --arch=armv7l to meego-image-creator.

Some servers (e.g. with squid as a proxy) may cache more aggressively than others, and as a result repomd.xml is invalid (old copy) and references out of date metadata files (primary, comps, filelists, etc). This is because the server is returning a cached/old copy of repomd.xml.
Proxy cache should be disabled in mic and yum.
$sudo mic-image-convertor --source-image=<your-netbook.img> --target-format=livecd --shell
This command will give you a chroot environment of MeeGo, you can follow the below steps to replace the default kernel with a new one.
1). remove the old kernel
# rpm -e kernel-netbook
NOTE: execute the above command in chroot environment.
2). copy new kernel to chroot environment of MeeGo
$sudo cp /path/to/kernel-*.rpm /var/tmp/imgcreate-*/install_root/
NOTE: execute the above command in your host system.
/path/to/kernel-*.rpm is your new kernel to install, /var/tmp/imgcreate-*/install_root/ is the directory where chroot MeeGo mounted on.
3). install the new kernel
# rpm -ivh /kernel-*.rpm # rm /kernel-*.rpm
NOTE: execute the above command in chroot environment.
After that, you can find out the new kernel in directory /boot/.
4). update contents of isolinux
$sudo cp /var/tmp/imgcreate-*/install_root/boot/initrd-*.img /var/tmp/imgcreate-*/iso-*/isolinux/initrd0.img $sudo cp /var/tmp/imgcreate-*/install_root/boot/vmlinuz-* /var/tmp/imgcreate-*/iso-*/isolinux/vmlinuz0
NOTE: execute the above command in your host system.
5. create an new image
#exit
NOTE: execute the above command in chroot environment.
After following all the above steps, you'll have a new image.
From version 0.20.1 on, mic2 can support btrfs, you can create btrfs image by change fstype=ext3 in your kickstart file to fstype=btrfs. A successful creation will depend on btrfs-progs (btrfs-tools on debian-based distros, btrfsprogs on openSUSE) and btrfs kernel module in your local system, the known issue is we can't create btrfs image on Fedora 11, the issue is the default btrfs kernel module has some issue which will make kernel panic, so for this case, you must ensure you have a stable & latest kernel and btrfs-progs 0.19 on your system, this needs you to build your kernel by yourself and use it to boot your system.
Btrfs-progs is a prerequisite tool, it includes /sbin/mkfs.btrfs, but its version must match btrfs kernel module, so you must ensure this, mic2 repo http://repo.meego.com/MeeGo/tools/repos/ has an issue which will install btrfs-progs 0.19 when you install mic2, this is an repo sync error, so please ensure you have your distro's btrfs-progs after mic2 is installed, if your distro's btrfs-progs version is 0.19, this isn't an issue, otherwise you must remove btrfs-progs installation introduced by mic2 and reinstall your distro's btrfs-progs.
How to build btrfs image on Fedora 11 or lower version?
Done, you're ready for creating btrfs image.
Meta-packages are discouraged in MeeGo. The preferred method is to use patterns in the repository (supported by both zypper and mic2). This is done by creating a patterns.xml file, which is a fairly simple XML file:
<?xml version="1.0" encoding="UTF-8"?>
<pattern xmlns:rpm="http://linux.duke.edu/metadata/rpm"
xmlns="http://novell.com/package/metadata/suse/pattern">
<name>meego-core</name>
<summary>MeeGo Core</summary>
<description>Packages needed for Compliance</description>
<uservisible/>
<category lang="en">Base Group</category>
<rpm:requires>
<rpm:entry name="pam"/>
<rpm:entry name="rootfiles"/>
<rpm:entry name="bash"/>
<rpm:entry name="sysvinit"/>
<!-- ...etc... -->
</rpm:requires>
</pattern>
The detailed documentation for this XML schema may be found on the OpenSuSe Wiki. There is also a Relax NG schema found in the source code for libzypp (buried in the folder zypp/parser/yum/schema).
In MeeGo's package-groups you can find several utilities, style sheets, and examples for how to create patterns and convert them to groups (comps).
Once you have both a patterns.xml and comps.xml file, you can create your repository like this. (For brevity, assuming a simple 'packages' repository.)
## Copy RPM packages to a folder, repos/ $ mkdir -p repos/repodata $ cp -f patterns.xml comps.xml repos/repodata $ createrepo -g repos/repodata/comps.xml repos/ $ modifyrepo repos/repodata/patterns.xml repos/repodata
Now GPG sign your repos/repodata/repomd.xml file. Note that `modifyrepo` is a part of the `createrepo` package.
