an auth/factotum is started by some initialisation code when you boot and
log in to your terminal.
on the cpu server, the same is true for the host owner (the owner of the
cpu service),
but then when you cpu(1) into a cpu server, your profile has a switch on
the service environment variable,
which is "cpu" for an incoming cpu call:

h% cat $home/lib/profile
...
switch($service){
case terminal
...
case cpu
...
bind /mnt/term/mnt/factotum /mnt/factotum
...
}

within cpu, the terminal's name space is available at /mnt/term, so it
simply binds the /mnt/factotum
in that name space onto /mnt/factotum in the cpu server, so you have all
your keys.

Note that this is a simple way in which the use of file servers to provide
system services and resources,
combined with 9P to import and export them, allows an interesting function
to be provided without having
any further code or special protocols.
