Comment 29 for bug 414996

okay... I think the issue might be more subtle. I tried installing lucid again via usb, hoping to be able to select the correct drive in the advanced options in the installation procedure... what I instead find is that when in livecd mode, gparted reveals my usb drive as /dev/sda, which I believe is selected as the default drive to install grub to, while my hard drive is /usb/sdb. I expect that after installation, this might be humongously problematic, since when the usb is removed, the hard disk would be reported as /dev/sda? Even though fstab would be set up using uuids as opposed to device location, many things, including grub, should expect to face issues upon update?

I also think this is closely related to the following bug:

Since this issue is not present in grub2 in karmic, this is certainly a regression.
