While I can't say I know for sure, your guess sounds like a good one. I usually have trouble with grub when I boot to a CD for recovery, and I believe this is on account of the chroot. I think it is because the /dev/<disk> information isn't available in the chrooted environment, so grub can't decide to use (for instance) hd(0,0). When I have trouble, I am typically installing grub, though, so I never see your error and can't be certain the situation is the same.

This of course failed initially due to some kernel bugs, but I was able to update to 2.6.18-133.el5virttest11xen from clalance's repo at RH. Now F10 i386 installs just fine, but of course I managed to neglect using kickstart to force the use of the PAE kernel. As a result, my domU won't boot. I could reinstall with KS but I thought now would be a good time to try to get my hands dirty and attempt to replace the kernel myself from the dom0. After some trials and tribulations with conflicting VolGroup names, I finally got my domU mounted under /mnt on dom0, copied in the PAE kernel RPM's, chroot'd to /mnt and ran rpm -Uvh. So far so good, but I then get the following error: # rpm -Uvh --force kernel-PAE-*.rpm warning: kernel-PAE-2.6.27.19-170.2.35.fc10.i686.rpm: Header V3 DSA signature: NOKEY, key ID 4ebfc273 Preparing... ########################################### [100%] 1:kernel-PAE ########################################### [ 50%] grubby fatal error: unable to find a suitable template 2:kernel-PAE-devel ########################################### [100%] Hmm, sure enough, /boot/grub/grub.conf wasn't updated! Now, I'm guessing I could add the new entry myself and all would be fine, but I'd like to understand why this isn't working... my theory is that grubby is confused by the chroot environment somehow and unable to properly locate my existing grub.conf file or templates? Any thoughts on this? A search hasn't yielded much in the way of answers...
