A couple clarifications/typofixes, lest I confound people...

I forgot to type -hdb /tmp/fc5stuffs in there.  And the explicit qemu
invocation was for illustrative purposes.  Really I'd use 
"vsys runimage <options> fc5genesis.iso", which is a wrapper with a
security enhanced version of the embedded vnc option that got added
recently to qemu (amongst other niceties).

Second, my comment below about implicit connection to sources, just
means that the default qemu invocation allows outgoing networking
through the host, thus you can pull the fedora repos from the net,
rather than providing them to the qemu system in another fashion.

Last, obviously fc5->fc5 is only illustrative.  fc5->fc6 or
fc5->latest_rawhide, might be more useful.  (perhaps combined with as
easy to use a method for distributing the build across many systems
running the same build hosts (in containers, via copying/sharing the
genesis .iso))

But of course all of this very much a second priority to simply besting
the featureset of ubuntu et al...  (and doing the multitude of cool
stuff with a livecd generator that is much cooler for end users than
the  genesis stuff)
