Public bug reported:
Binary package hint: grub
Ubuntu 8.04, i386, alternate install CD.
I upgraded from Ubuntu 7.10 to 8.04. I used alternate CD, I upgraded
from working 7.10 that was up and running. I inserted CD with 8.04 and
upgrade was offered to me and I accepted it. Upgrade took long time but
after several hours system was finally upgraded. After reboot I saw
updated grub menu and when I selected default option, I met kernel panic
after several seconds.
After investigation I found that initrd line was missing in
/boot/grub/menu.lst in new records for 8.04
state of menu.lst after upgrade, notice missing initrd line in
2.6.24-16-generic records:

I added line with initrd and problem is fixed. An example:

This is a critical bug for new Linux users they cannot recover from my
point of view... I am not sure if this bug is in grub package or in
other package.
