I don't think build time is appropriate.  Constructing a livecd on my
workstation takes about 10-15 minutes, and is not even guaranteed to
succeed.  This happens in the case where there's dep problems in the
distribution.  Then just running the handful of test cases I've got now
takes at least another 10-15 minutes.  Once we have fifty or sixty test
cases, we could be talking several hours of runtime.

I definitely understand the desire to have it run at package build time,
which is one reason why I'd like to add support for running out of git.
We could at least rig up automatic builds then and get some of the same

No, I was not aware of this until right now.  This could be extremely
handy stuff, though.  Is there any way to create fake hardware RAID
devices, too?
