na página de manual :
pmount ("policy mount") is a wrapper around the standard mount program
which permits normal users to mount removable devices without a match-
ing /etc/fstab entry.
pmount is invoked like this:
pmount device [ label ]
This will mount device to a directory below /media if policy is met
(see below). If label is given, the mount point will be /media/label,
otherwise it will be /media/device.
