Yeah, but I think it's not related.  That bug and the screenshots show
a kernel booting, then failing to mount.  Are you seeing a failure in
the initial loader, George?  And as noted, the issue I'm seeing is
new in 12.1, as compared to the loader in 12.0

Yeah.  I was hoping for an easier path, but.  I can try slogging back
through stable-12 a month or two at a time.  Is moving through svn by
date the easiest path, or are there [stable] revision tags that would make
it easier?

Thanks all.

ps, somewhere earlier in this thread that I lost right now someone asked
if I could put an alternate versions loader on an ISO.  I don't know that
I know how, but I'd be happy to try it.
