LVM already identifies PVs using UUIDs, so if you are using
anything-on-LVM-on-md, you need not worry about device names anyway.

dm-crypt currently needs to be told explicitly to use a base device
using /dev/disk/by-uuid if you want it to be flexible.

The only issue homehost protects against, I think, is machines that
use /dev/md0 directly from grub.conf or fstab.
