Bug#566965: No way to boot using UUIDs

[Christoph Anton Mitterer]

Hi.

Regarding the bug itself.

It seems that the initramfs-script simply misuses the root= kernel
parameter.

AFAIK, the device specified at root= is simply the "finalised" device
where the root-filesystem itself is found.
So e.g. /dev/sda1 if it's directly on it,.. or /dev/vg00/lv00 if it's
directly on lv00,...


I think lvm2 should do the following (at least regarding
initramfs-images):
- The hook script should check, whether the root-fs as specified in
fstab is directly or indirectly on an LV (guess it's quite complex to
really find that out).
If so,.. it includes /sbin/lvm

- The boot script, should first check if /sbin/lvm is there,... and if
so, unconditionally to lvm vgchange -an


I guess the init-script should still scan, as further devices may have
appeared.


Cheers,
Chris.
