Package: grub-common
Version: 1.97+20091125-1
Severity: important
File: /usr/bin/grub-mkrelpath
In my filesystem, /boot is on a separate partition (/dev/sda1) and all
the other partitions are on LVM. grub used to determine that this
correctly and set up /boot/grub/grub.cfg to reference /boot/vmlinuz* as
/vmlinux*, and likewise for the initrds. However, recently grub has
been referring to /boot/vmlinuz* in the grub.cfg file, which is not
valid (since the kernels are in the root of that partition, not under a
directory).
I ran /etc/grub.d/10_linux under sh -x and determined that
"grub-mkrelpath /boot" responds with "/boot" instead of "/". This is
called by make_system_path_relative_to_its_root. This buggy behavior is
also true for other (LVM) volumes:
lakeview ok % grub-mkrelpath /boot
/boot
lakeview ok % grub-mkrelpath /usr
/usr
lakeview ok % grub-mkrelpath /boot/grub
/grub
lakeview ok % grub-mkrelpath /usr/bin
/bin
As a consequence, every boot requires manual intervention. This is
merely an annoyance for me, but it precludes the ability to boot the
system for my boyfriend, since he has no clue how to fix the problem.
My /boot/grub/grub.cfg:
