This is the stuff that my literal mind copes poorly with :-) I would
never have picked this up.  If you don't mind, there's more
clarification I need on this issue: how is the sshserver process
running as "none" going to upgrade to, say, user "lucio"?  Is this a
result of the exchange of credentials, using the "capabilities"
driver?  If it is, there's a depth of cleverness in the new Plan 9
security model that I had missed until now, namely the elimination of
the intermediate "superuser" step required by the Unix paradigm.  I
guess I ought to have figured it out before now...

And another equally silly question, maybe there's someone else out
there that can learn from my mistakes and/or ignorance: the factotum
on the CPU server does not contain all the keys "eve" is entitled to,
in fact, it only contained a key that could be constructed from the
NVRAM contents (what does the !hex=?  entry represent?).  It's
possible that the secstore was not accessible to "eve" on boot (I've
extended the expiry date as soon as I discovered it had lapsed), is it
a given that the CPU server's factotum is invoked with the "S" option
or should I check somewhere to make sure before I reboot the server?
