I think I have experienced another facet of this bug. I had Jaunty
installed in /dev/sda with a separate /boot partition. When I installed
Karmic on another partition (also on /dev/sda) and *not* using the /boot
partition for Karmic, the resulting grub.cfg created entries for Jaunty
that ignored the separate /boot partition. In other words, In other
words, it produced:
menuentry "Ubuntu 9.04, kernel 2.6.28-15-generic (on /dev/sda6)" {
insmod ext2
set root=(hd0,6)
search --no-floppy --fs-uuid --set 7f69072f-cea2-4ec3-bde9-81dd16744034
linux /boot/vmlinuz-2.6.28-15-generic
root=UUID=7f69072f-cea2-4ec3-bde9-81dd16744034 ro quiet splash
initrd /boot/initrd.img-2.6.28-15-generic
}
when it should have been:
menuentry "Ubuntu 9.04, kernel 2.6.28-15-generic (on /dev/sda6)" {
insmod ext2
set root=(hd0,6)
search --no-floppy --fs-uuid --set 9bdeb391-8fd9-48b1-9316-c4a00b7fa7a2
linux /vmlinuz-2.6.28-15-generic
root=UUID=7f69072f-cea2-4ec3-bde9-81dd16744034 ro quiet splash
initrd /initrd.img-2.6.28-15-generic
}

This was on the Karmic beta Desktop CD as of 2009-10-06. Following work
around (which will require manual editing of grub.cfg every time I run
'update-grub on Karmic) I installed grub-pc on Jaunty and found that it
did appear to produce grub.cfg compliant with a separate /boot partition
when run from that installation. I'm not certain that the Jaunty
grub.cfg is correct for Jaunty (which does not use the /boot partition.)
It produced the entry:
menuentry "Ubuntu, Linux 2.6.31-12-generic (on /dev/sda9)" {
set root=(hd0,9)
linux /boot/vmlinuz-2.6.31-12-generic
root=UUID=836c9f55-820b-4760-b2cb-81af5b6fedfe ro quiet splash
initrd /boot/initrd.img-2.6.31-12-generic
}
If that uses the search line for Jaunty it will not find the kernel or
initial RAM disk as those are not in the /boot partition.
