I'm sort of on the fence about it.  On the one hand, it is quite convenient to
get swap for "free" if you happen to boot the PXE image on a machine that
already has an OS on the hard drive.  On the other hand, things like clustering
and full administrator control are important, so we don't necessarily want to be
doing things behind the admin's back.  Can we disable the scanning by default,
but add a PXE boot option to enable the scanning for developers?
