I don't know whether this really is a bug in initrd-tools or rather a
bug in lvm-common.

I just ran into trouble because there is an lvm snapshot of the /var
partition but since the module dm-snapshot was not automatically loaded
at boot time the kernel was not able to mount /var.

I helped me in adding following line after line no. 10 in
/etc/init.d/lvm:

modprobe dm-snapshot >/dev/null 2>&1

An other solution to this problem would be to add dm-snapshot to
/etc/modules, but I don't believe that this would be the best solution
for this bug.

I suggest to reassign this bug to lvm-common and to fix the bug there.

Have a nice day
