Just for a wild guess:

1) on g, your profile mounts /mnt/term/mnt/factotum onto /mnt/factotum
2) on larch, your profile mounts /mnt/term/dev into /dev

At least, that would have the effect you see.  There are a few other ways.

that will happen if both factotums have the key for a different user.
they agree on that key and the remote automatically "becomes" that
user..

for a better treatment see:

Hi,

I don't understand quite what is happening here.

I have an account steve on my machine. I have run the cpu and
keyfs listners so I can cpu to this machine.

Now I cpu to one of the 9grid machines - where I am known as
steve.simon.

	term% cat /dev/user
	steve
	term% cpu -h g.grid.bell-labs.com
	cpu% bind /mnt/term/net /net
	cpu% cpu larch.snellwilcox.com
	term% cat /dev/user
	steve.simon
	term%

IE. I have come back to my machine, authenticated via the auth server on
a.grid.bell-labs.com - though I don't know how, only to appear as somone
else and of no-longer the owner of my files.

How did I authenticate for this reverse connection?
If I had the same username at both end would I have
rights to my files? (and should I have?)!

confused

-Steve
