Comment 128 for bug 568050

Hello,

First I would like to thank Phillip.

I have tested the patch further an alternate install by rebooting using the cd and choosing to rescue a broken box.
Than going in the launch a shell and remount all FS in place and add ppa, update, upgrade.
It doesn't help.
I have also recreated the initrd to ensure the new lib is included in.

For me the bug is a combination of parted/dmraid and grub2.

Past the cosmetic issue with ubiquity/parted the install can continue. (Using the trick of renaming devices)
I can install grub2 on /dev/mapper/isw_<aname>_Vol00 which is my fakreaid.

But and than I have 2 random options :
While choosing a linux entries it just point in the void and restart instantly or it finds a kernel boot it and crash on an unable to mount root.

And if I cheat by installing grub2 on /dev/sda and /dev/sbd which is finally what would happen if I install on /dev/mapper/isw_...
Than I can boot but and here is the but my root is falling on /dev/sda which tends to proof that there is something very weird in the initrd that doesn't create properly the /dev/mapper/isw_... and once booted I can't reassemble it as /dev/sda is already used as root.

I have also tried to create and extra entry in grub 2 adding a break=mount but it doesn't work even if the same trick works on a vmware using 10.04...

Hope this helps for further debug.

Regards,
