Bug#476531: grub-pc: unable to use LABEL=root for root device

[Michael Spang]

Package: grub-pc
Version: 1.96+20080228-1
Severity: wishlist

Before grub2, you could set the root device to "LABEL=root" in menu.lst.
This might be necessary if, say, you switch to/from kernels that use
libata for PATA controllers. A kernel with libata would name the first
PATA disk "sda", whereas previous kernels would name it "hda".

It would be great if there was an option to make 10_linux use filesystem
labels instead of the device name.

Thanks,
Michael Spang
