Bug#609590: grub-common: 10_linux use /dev/root as device

[Daniel Dehennin]

Package: grub-common
Version: 1.99~20110106-1
Severity: normal

Hello,

Updating to experimental break boot, is use root=/dev/root which seems
to be unsuported by my kernel. Note that I do not use initramfs.

Previous version use root=/dev/sda2.

Regards.
