I think support for GUID=foo in /etc/fstab for mount would be pretty easy.
Having it in ther kernel would be nicer and shouldn't be that difficult,
on the other hand it'll need a consensus on wether the kernel should look
at every partition on startup - IIRC some people where opposed to such
soloutions in the past.

Of course it doesn't work. We've performed a software upgrade.
