Bug#486804: grub-pc: grub.cfg has wrong root device set on LVM with /usr on a different lv than /

[florian kriener]

Package: grub-pc
Version: 1.96+20080617-1
Severity: important


After an upgrade I could no longer boot my system without editing the menuentry with grup.

After changing

	linux	/boot/vmlinuz-2.6.24-1-amd64 root=UUID=3fe734d5-bbaf-4515-835e-f6d0bb12e242 ro single vga=791
	initrd	/boot/initrd.img-2.6.24-1-amd64

to

	linux	(hd0,2)/boot/vmlinuz-2.6.24-1-amd64 root=UUID=3fe734d5-bbaf-4515-835e-f6d0bb12e242 ro single vga=791
	initrd	(hd0,2)/boot/initrd.img-2.6.24-1-amd64

my system booted as usual.

I suspect

   set root=(vg-usr)

to be the culprit here.
