# vchanger-umount-uuid.sh ( vchanger v.1.0.3 ) 2020-05-06
|
|
#
|
|
# This script is used to unmount the filesystem having the
|
|
# UUID specified in parameter 1. The mountpoint 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.
|
|
#
|
|
# Generally, this script is designed to be invoked by a
|
|
# launcher script, vchanger-launch-umount.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.
|
|
