This got filed relatively recently and fixed up.  For F9-based images,
though, you'll have to do a workaround of removing
the /etc/udev/rules.d/50-udev-default.rules.rpm* (or at least, move them
out of the way)

That sounds like something more general and not live image specific.
It'd be worth getting a ctrl-alt-delete in there to reboot and then boot
into runlevel 3 so you could grab some logs to file against X

This is the case and unfortunately, with things currently in the kernel,
I don't really see any way around it.  Modulo writing some tool to
(likely offline) analyze and rewrite the snapshot file.  But relatively
deep dark voodoo required to write such a tool
