Thanks, that's a very interesting idea, I will try that and let you
know.

Looking thru the manpages, I don't see any provision for adding AND / OR
logic to keys (e.g require both passphrase AND keydisk to boot, require
passphrase OR keydisk, etc) the way Linux cryptsetup provides, at least,
OR-logic across multiple keyslots.

(Having multiple keyslots on an encrypted volume has saved me a few
times!)

Is there anything like this in OpenBSD?
