It's possible but unlikely that loader is corrupted. I had the same
problem a few months ago under 4.9. Plus, I already made world, so that
should have built a fresh version, but it's doing the same thing as the
stock 4.10 install.

Any critical reason for doing this, other than giving me the options found
in loader?

Yep. That's what I can't figure out. Is boot2 doing something different
on a non-root directory because I'm on a RAID controller instead of a
regular ad or da device?
Oh, I just realized that it can't be a corrupt loader - when I moved it to
/ it woke up fine.
I know some assembly, but I can't readily make heads or tails of boot2.
Is that beyond the scope of freebsd-stable?
Thanks again for any help.
