Right now we don't, but that's something that I'm pretty convinced needs
to change anyway.  We just need to be sure AUTOSWAP=yes
in /etc/sysconfig/init and then the right thing will happen.  And
probably add an override for disabling it.

Doing something like this would tie in a bit with some of the persistent
change work that Douglas McClendon is working on.  It's not that
different in what's being done, so it probably makes sense to just
extend that infrastructure.  Asking is a little trickier, just because
of input, locales, etc...  but if we're even to where we can use it
automatically and you just have to do a certain setup in advance, it's
not too bad I don't think.  At least for at first
