Not true, the permissions are quite relaxed (at least, this agrees
with my experience):
tickle% ls -ld /mnt/factotum
d-r-xr-xr-x M 642 proxima proxima 0 Nov 27 17:14 /mnt/factotum
tickle% ls -l /mnt/factotum
-lrw------- M 642 proxima proxima 0 Nov 27 17:14 /mnt/factotum/confirm
--rw-r--r-- M 642 proxima proxima 0 Nov 27 17:14 /mnt/factotum/ctl
-lr-------- M 642 proxima proxima 0 Nov 27 17:14 /mnt/factotum/log
-lrw------- M 642 proxima proxima 0 Nov 27 17:14 /mnt/factotum/needkey
--r--r--r-- M 642 proxima proxima 0 Nov 27 17:14 /mnt/factotum/proto
--rw-rw-rw- M 642 proxima proxima 0 Nov 27 17:14 /mnt/factotum/rpc
I presume that the actual server is applying discretion :-)
tickle% cat /dev/user
luciotickle% cat /mnt/factotum/ctl
++L
