It's still not as clean as I would like it, but at least I understand
(most of) the current failures.  I'll probably not get another chance to
look at this until Monday, though.

First boot and auto-relabel works fine.

Second boot generates the following audit warnings:

   type=1401 audit(1380309719.391:4): security_validate_transition:  denied for oldcontext=system_u:object_r:device_t:s15:c0.c1023 newcontext=system_u:object_r:framebuf_device_t:s0 taskcontext=system_u:system_r:initrc_t:s0-s15:c0.c1023 tclass=chr_file

   udevd[86]: setfilecon /dev/vcs2 failed: Operation not permitted

   udevd[93]: setfilecon /dev/vcsa2 failed: Operation not permitted

I initially sunk a lot of time into these until I realized the problem
is present (and just not reported) in master.  I haven't yet opened a
bug on it, but I intend to unless I can fix it myself (or someone sends
me a patch) in the very short term.

Subsequent boots are less happy:

   done.

But these are all due to problems I detail in "udev/init: work around
dev-cache restore problems".  There's a simple workaround for it, but
it's hacky (less hacky than not using the dev cache at all? more? not
sure) so I'd rather come up with a cleaner solution.

Anyway, that's the state of meta-selinux's master-next as of right now.

As mentioned (somewhere) elsewhere, master-next will continue to be
non-ff for the foreseeable future, so anyone else should use it with
caution.  master is, of course, perfectly stable (and I hope up-to-date
with all current submissions merged).
