grub2 does not properly deal with seperate boot partition

[Tom Bogue]

Binary package hint: grub2

I set up my computer with a separate boot partition on /dev/sda1 (in the hopes of speeding my boot) mounted as /boot. However, the grub.conf created by update-grub refers to files relative to the root parition (/dev/sda8 on my system). For instance, line 9 states

if [ -s /boot/grub/grubenv ]; then
  have_grubenv=true
  load_env
fi

the problem is, on the boot partition grub2 boots from, the file is properly refered to as /grub/grubenv. Thus grub fails to think it has a grubenv. I should note that grub2 actually properly deals with the partition internally. Or at least if I comment out the if statement, leaving

#if [ -s /boot/grub/grubenv ]; then
  have_grubenv=true
  load_env
#fi

Things work as they should. (at least as far as my default boot entries are concerned). So the problem really lies in /etc/grub.d/00_header, where the if statement is generated. But a similar issue might be in other /etc/grub.d files as well.

I'm running Ubuntu 9.10, and grub2 1.97~beta4-1ubuntu4.1.

Thanks for your report. We fixed this in Lucid as bug 478035; I hope to get round to backporting that fix to Karmic at some point ...
