yes:

$ ls -al /home/mexas/mnt/
total 8
drwxr-xr-x   2 mexas  wheel   512 Mar 30 22:00 .
drwxr-xr-x  43 mexas  wheel  2048 Mar 30 22:24 ..
$ 

One thing is slightly not clear.
Examples in devfs.conf(5) man page are
quite different to the handbook.
Perhaps the devfs.conf man page is outdated.
I see lots of examples on the net from 5-10
years ago, all similar to devfs.conf style,
e.g.:

http://www.cyberciti.biz/faq/freebsd-allow-ordinary-users-mount-cd-rom-dvds-usb-removabledevice/

own       /dev/da0       root:operator
perm      /dev/da0       0666

which is different to the handbook, which
has:

[localrules=5]
add path 'da*' mode 0660 group operator

HOwever, I tried adding the "own/perm" lines
to devfs.conf too, still no luck.

Many thanks
