Subject: [PATCH 3/7] Avoid automounting volumes on virtual and unknown buses

Basically we want to avoid automounting volumes from

 1. drives on a 'virtual' or unset bus
 2. volumes without a drive

This is to avoid interference with things like Fedora's livecd-tools
that use device-mapper to set up images. See

 https://bugzilla.redhat.com/show_bug.cgi?id=494144 for more

background.

In the future we might want to relax 1. so automounting things like
Linux MD and LVM2 devices work.
