Bug#568084: grub-common: Use of LABEL for 'root='

[nutzteil]

Package: grub-common
Version: 1.98~20100115-1
Severity: wishlist
Tags: patch



Patch for /etc/grub.d/10_linux,
so you can use LABEL beside UUID and devices.

Activation in /etc/default/grub with:
GRUB_DISABLE_LINUX_UUID=true
GRUB_ENABLE_LINUX_LABEL=true

Thanks
christian
