My udev-fu is quite low - if that's possible, I'm happy with it as well.
The goal is to avoid distro-specific init scripts.

However, vgchange is at the very end of fedora-storage-init, so we could
simply add dependencies to run mdadm (when later someone writes service
files for that) before vgchange and that would work as well.

A fixed execution order is already there with the current shell scripts,
as far as I understand.

Thanks.
