I've done that, too, just forgot to mention it. So there's still some
other problem.

Well, found the problem now:

I've been using "file -s /dev/XXX" to get the UUID. But that truncates
the UUID (in cases where output would exceed n characters?). *Sigh*.
Works now.

Ah, thanks; good to know for next time (if I'll remember; I've started
using Linux long before uuids were being used, so my brain is wired
the old way where my doing would have worked without issue; note to
self: need to change wiring).
