Bug#513504: flash-kernel should handle LVM roots better

[Paul Jakma <paul+debianbugs@jakma.org>]

Package: flash-kernel
Version: 2.12
Severity: critical
Justification: breaks the whole system

LVM roots are not handled well. If one specifies an LVM root in 
/etc/fstab in the form of /dev/vg/lv (e.g. /dev/VG-n2100/root_lv) 
then the system will fail to boot. Instead, one must use the 
/dev/mapper/VG-vg-lv form in fstab.

The problem, according to waldi/maks on #debian-kernel is that the 
/dev/vg/lv form devices are just symlinks to the /dev/mapper devices. 
These symlinks do not exist when initramfs goes to mount the root. 
(If I /understood correctly).

A workaround, according to tbm, would be to have flash-kernel 
canonicalise LVM devices to their /dev/mapper/... form - I gather.
