>From what I could tell, the UUID was simply never tracked down. I didn't
investigate too much -- net user-visible result is, the machine hangs in
the initramfs for several minutes before it finally concludes that it
couldn't find anything to mount the root filesystem with.

It could be that the UUID code doesn't know to track RAID at all, and
only looks at devices that were available at kernel boot time, before
the initramfs?

What I can tell you is that they're just about completely redundant for
RAID configurations, among other things. If I already have an mdadm.conf
which I'm using to build the cluster -- or a crypttab which I'm using to
build the md-crypt device -- or even some md kernel autodetection, based
on UUIDs and metadata stored in the physical volumes...

In all of these cases, the actual device I am mounting is going to be
the same, every time, as it is hardcoded *somewhere* -- the underlying
physical volumes may or may not have been setup by UUID. If they have,
then why do UUID stuff twice? If they're setup by /dev/sd*, then there's
not much point in using UUIDs higher up the chain.

As for assigning someone else to the bug, at the very least, it was an
email that I found in the source file in question. Still, if I wasn't
supposed to do that, I apologize.
