[PATCH] rebootless installer / live migration support for mayflower

[Douglas McClendon]

In the name of release-early-release-often, here is an untested patch to 
livecd-tools mayflower script, which I believe adds support for rebootless 
installation.

A proof of concept rebootless installer should hopefully be forthcoming in a day 
or so, and an anaconda based one in a week or so.

Note, that the prior patch I had, was actually missing a --force flag on the 
mdadm build command.  But don't worry, mdadm is out of the picture since it's 
--grow feature wouldn't work for me.  This patch is far superior, and is a 
successful implementation of the theoretical workaround #4.

I leave it as an excercise for the reader how to perform a rebootless 
installation manually ;)
