Many Linux users would like to try MeeGo, here is a convenient method to install a MeeGo to hard disk.

Key word: mount, rsync

Warning!! Be careful not overwrite useful data on your existing system!

Warning!! Following just provides a clue to install OS quickly, you should be responsible for your actions!

Preparation

  • Download an netbook image or IVI image to hard disk. 
[root@woliu-desktop img]# ls
meego-netbook-ia32-trunk-daily-1.1.80.14.20110107.1.img
  • Create an empty partition, format as ext3, 
[root@woliu-desktop img]# fdisk -l

Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xd274d274

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        6375    51207156    7  HPFS/NTFS

    • 4G is enough to experience it. The larger, the better.
    • Don't care about the file system. ext3 is OK
    • Here, I use /dev/sda9 as the destination to install MeeGo

Create file system

  • Mount the image to get installation source 
mkdir /mnt/{1,2,3}
mount -o loop /work/img/meego-netbook-ia32-trunk-daily-1.1.80.14.20110107.1.img /mnt/1/
mount -o loop /mnt/1/LiveOS/squashfs.img /mnt/2/
mount -o loop /mnt/2/LiveOS/ext3fs.img /mnt/3/

Now we get the source 

[root@woliu-desktop img]# ls /mnt/3/
bin  boot  dev  etc  home  lib  lost+found  media  mnt  opt  proc  root  sbin  srv  sys  tmp  usr  var
  • Mount the empty partition for install MeeGo 
mkdir /mnt/4
mount /dev/sda9 /mnt/4
  • Copy files 
rsync --avz --delete /mnt/3/* /mnt/4/

Add boot item to boot config

  • Modify fstab 
[root@woliu-desktop img]# vi /mnt/4/etc/fstab
/dev/root  /         ext3    defaults,noatime 0 0
devpts     /dev/pts  devpts  gid=5,mode=620   0 0
tmpfs      /dev/shm  tmpfs   defaults         0 0
proc       /proc     proc    defaults         0 0
sysfs      /sys      sysfs   defaults         0 0
  • Modify boot item for existing boot loader
    • prepare the kernel 
cp /mnt/4/boot/vmlinuz-2.6.37-6.3 /boot
    • Add boot option

I use grub2 with Ubuntu 10.10, so I have to add this to my grub.conf at /boot/grub/grub.cfg 


menuentry 'meego' --class ubuntu --class gnu-linux --class gnu --class os {
        recordfail
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos9)'
        search --no-floppy --fs-uuid --set 81273c8f-9ad0-47b2-a3a5-5041944201d2
        linux   /boot/vmlinuz-2.6.37-6.3 root=/dev/sda9
}

Boot to MeeGo

Restart the machine, and choose boot option "MeeGo", you should be able to boot it.

Note

I have to re-install MeeGo frequently and I'd like to keep two different versions of MeeGo for comparison. So I find this way to update MeeGo effectively.

To mount livecd image, using rsync to update file system contents, a trivial modification of configurations. That's all.
