pumount − umount arbitrary hotpluggable devices as normal user
pumount [ options ] device
pumount is a wrapper around the standard umount program which permits normal users to umount removable devices without a matching /etc/fstab entry.
pumount also supports encrypted devices which use dm-crypt and have LUKS metadata. If a LUKS-capable cryptsetup is installed, pumount will umount the mapped device instead and call cryptsetup to close the decrypted device afterwards.
pumount expects the device as its only argument. This will umount device from a directory below /media if policy is met (see below).
Important note for Debian: The permission to execute pumount is restricted to members of the system group plugdev. Please add all desktop users who shall be able to use pmount to this group by executing
adduser user plugdev
(as root).
−l, −−lazy
Lazy unmount. Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore. (Requires kernel 2.4.11 or later.)
−h, −−help
Print a help message and exit successfully.
−d, −−debug
Enable verbose debug messages.
−−version
Print the current version number and exit successfully.
The umount will succeed if all of the following conditions are met:
|
• |
device is a block device in /dev/ (it does not need to exist if −l is supplied) | ||
|
• |
device is not in /etc/fstab (if it is, pmount executes umount device as the calling user to handle this transparently) | ||
|
• |
device is mounted according to /etc/mtab and /proc/mounts with the calling user’s uid | ||
|
• |
mount point is in /media |
