Bug#633024:

[Roel Brook <rainmaker52@gmail.com>]

OK, I've tried udevadm settle, and it didn't do anything.

I (think) I did find the place where the race condition is actually
occurring.

The mdadm array it's assembling, is partitioned. Partition 3 is the PV
which holds the LV with my root filesystem.

The "lvm" top-script is ran immediately after the mdadm script. The
mdadm script should actually take some time to settle and let udev
create all partition devnodes, or else LVM (or any other volume manager)
will not pick up on the existence of partitions.

Sincerely,
Roel Brook
