I didn't realise v9fs ever had auth support. Here is how I've been
getting an authenticated mount for years:
# create mountpoint
$ n=$HOME/n
$ mkdir -p $n/wren
# need factotum running to do the dirty work
$ factotum
# srv -a posts a pre-authenticated socket in the p9p ns directory
# wren is my fileserver
$ srv -a wren
!adding key: role=client proto=p9sk1 dom=sqweek.dnsdojo.org
user[sqweek]:
password:
$ 9mount -i 'unix!/tmp/ns.sqweek.:0/wren' $n/wren
(or)
$ mount -t 9p -o uname=sqweek,trans=unix,noextend,dfltuid=$(id
-u),dfltgid=$(id -g) /tmp/ns.sqweek.:0/wren $n/wren
# I'm not sure if uname is strictly necessary
$ 9bind $n/wren/home/sqweek/mail $HOME/sqweek/mail
# various other binds
Jorden mentioned it's a bad idea to let anyone mount anything because
everyone shares the same namespace. 9mount does have some sanity
checks for that environment, it will only let you mount over a
directory you have write access to (and isn't sticky) or is under your
home dir. Never really been field tested though :)

Can't help you there - I'm not sure it makes sense to try and put
factotum's functionality in the linux kernel... Is there some problem
with the private namespace/individual user mount approach?
