I think the best dependency would be on
udev (>= 0.059) | hotplug
This way we both satisfy sarge (who will need hotplug) users and sid users (who
will install udev). Also backports users are fine!

Not needed: if their version is too old, then it doesn't satisfy the dependency
and hotplug must be installed...

I think we shouldn't build-depend on hotplug... Especially since udev both
provides it and conflicts with it, and so we son't ever be sure it's really
there, and it's not udev instead...

Let's just do as you say and call "make hotplug-install" & "make udev-install",
at least for now!
