# vchanger-mount-uuid.sh ( vchanger v.1.0.1 ) 2015-06-03
|
||
|
|
#
|
||
|
|
# This script is used to mount the filesystem having the
|
||
|
|
# UUID specified in parameter 1 at a fixed path. The path
|
||
|
|
# will be a subdirectory of the path given by the MOUNT_DIR
|
||
|
|
# environment variable, where the UUID is used as the
|
||
|
|
# subdirectory name. The MOUNT_DIR variable is sourced from
|
||
|
|
# /etc/default/vchanger or /etc/sysconfig/vchanger. Also,
|
||
|
|
# the MOUNT_OPTIONS variable may be set to specify additional
|
||
|
|
# options to pass through to the mount command.
|
||
|
|
#
|
||
|
|
# Generally, this script is designed to be invoked by a
|
||
|
|
# launcher script, vchanger-launch-mount.sh, that is itself
|
||
|
|
# launched directly by udev in response to a hotplug event.
|
||
|
|
# This is useful for headless systems that do not have an
|
||
|
|
# automount capability such as Gnome Nautilus, but have
|
||
|
|
# non-root daemons that require plug-n-play attachment of
|
||
|
|
# external disk drives.
