Ah, sorry. I didn't read your post carefully enough and saw pmount when you were using pumount. Using sudo for that makes sense. > Now try > for a general solution.

It's exactly the same problem when udev is used to mount a device, which is why I prefer to have a process running as the logged in user doing that, whether it be something incorporated into the DE or a separate daemon started from ~/.xinitrc. It gets messy if you are running a multi-seat system, but if only one user is running X at a time, it is the cleanest way. Of course, as you are having mdev run a script, you could get that script to check which user is logged into X and use su to mount it for them, avoiding the umount issues. -- Neil Bothwick Like an atheist in a grave: all dressed up and no place to go.
