Revision as of 13:05, 7 July 2011

MeeGo Image Creator is the tool we use to create MeeGo images. Here are the simple steps on how to create a MeeGo image. For more in-depth information, go to the main Image Creator developer's guide: Image Creation

Creating a MeeGo Image

STEP 1 - Install Meego Image Creator (MIC)

To install it:

• on OpenSuse

sudo zypper addrepo http://repo.meego.com/MeeGo/tools/repos/opensuse/11.4/ meego-tools
sudo zypper install mic2

• on Fedora

add repo like this:

# 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

add gpg key:

# gpg2 --keyserver subkeys.pgp.net --recv 0BC7BEC479FC1F8A
# gpg2 --export --armor 0BC7BEC479FC1F8A > /etc/pki/rpm-gpg/RPM-GPG-KEY-meego

Install mic2:

# yum install mic2

• on MeeGo

sudo zypper addrepo http://repo.meego.com/MeeGo/tools/repos/meego/1.1/ meego-tools
sudo zypper install mic2

• on Ubuntu or Debian:

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/ /

Install mic2:

$sudo apt-get update
$sudo apt-get install mic2

• Download MIC source from Gitorious:

http://meego.gitorious.org/meego-developer-tools/image-creator

More on installation dependencies and options on downloading MIC, go to the 'Installation' section here: Image_Creation#Installation_Requirements

STEP 2 - Get MeeGo .ks File

KickStart (.ks) configuration files are passed to MIC to create 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.

The official MeeGo .ks files are here:

Formal release: http://repo.meego.com/MeeGo/releases/1.2.0/builddata/image-configs/

Weekly build: http://repo.meego.com/MeeGo/builds/trunk/latest/builddata/image-configs/

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.

For details about how to modify the ks file, please refer: http://wiki.meego.com/Image_Configurations_-_KickStart_Files

STEP 3 - Create MeeGo Livecd Image

MIC has to be run with root privileges using 'sudo'.

Here is the command to create a MeeGo livecd image you can burn onto a CD.

sudo mic-image-creator --config=default.ks --format=livecd --cache=mycache

A file named meego-1.2-default-XX.iso is created. This ISO image is a hybrid image and can be either written to a disk device or burned onto a cd.

STEP 4 - Create MeeGo LiveUSB Image

To create a MeeGo liveusb image that you can transfer to a USB stick.

sudo mic-image-creator --config=default.ks --format=liveusb --cache=mycache

A file named meego-1.2-default-XX.usbimg will be created. To burn it onto a USB stick, run the following command:

sudo mic-image-writer meego-1.2-default-XX.usbimg

This image has a FAT file system and can be mounted easily on Windows and other OSes.

Configure Proxy and Other Variables

~/.mic2.conf is a configuration file that can make your life easier by specifying proxy settings, cache directories, and other variables that you normally would have to re-type in your command-line.

Copy and paste this into a file called: ~/.mic2.conf

Replace with your own relevant values.

[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.

Note: When specifying proxy and no_proxy, you do not need to use the --proxy flag in your .ks files when referring to repos.
