[9fans] v9fs authentication question

If I want to be able to use v9fs to mount a plan9 fileserver as a specific
user, do I need to provide credentials via plan9port factotum?

Drawterm takes an argument about which authentication server to talk to,
but the directions I see for v9fs seem to only talk about USER environment
variables, or mounting a factotum interface.

If you want to mount as a specific user, you can specify the
"uname" option of v9fs.

See the documentation:

https://www.kernel.org/doc/Documentation/filesystems/9p.txt

Example:

$ mount -t 9p -o tcp,trans=tcp,uname=djc 135.104.24.18 /n/sources

If you require authentication, you'll need to authenticate
with factotum.

Example:

$ factotum -n
$ srv -a -k user=djc sources.cs.bell-labs.com
$ mount -t 9p -o unix,trans=unix,uname=djc $(namespace)/sources.cs.bell-labs.com /n/sources

yes.  in p9p, srv initiates auth and expects factotum to negotiate it.  i
use this (it is from a man page and/or wiki page; i forget):

#!/bin/bash

factotum -n
srv -a bootes bootes
sudo mount -t 9p -o trans=unix,uname=$USER,dfltuid=`id -u`,dfltgid=`id -g`
`namespace`/bootes /mnt/bootes
