Release criterion proposal: live image persistence

During the F17 cycle, we found that live image persistence was broken:

http://bugzilla.redhat.com/show_bug.cgi?id=740280

and further found that there was no criterion covering this. At the time
the issue was first discussed, we agreed we should add a criterion to
cover live image persistence. (In later evaluation of the issue we kind
of lost that thread, but I believe the decision still stands).

So, I'm proposing a criterion for Final:

* It must be possible to create a USB stick from a live image, using the
appropriate Fedora tool, with a persistent storage overlay for the
entire system and/or a separate overlay for the /home directory

As things stand this basically requires that it must be possible to use
--overlay-size-mb and --home-size-mb with livecd-iso-to-disk
successfully. Both features are important for some use cases.

Thoughts? We could theoretically require only the whole-system overlay
to work, not the separate /home overlay, but the separate /home overlay
possibility exists for a good reason - the whole-system overlay is very
easy to exhaust, so if you're going to try and use a persistent stick
for long-term use, it's much better to also/only have a separate /home
overlay, which is implemented in a way that's much less prone to space
exhaustion. Thanks!
