# Kills any processes within the mounted location and
|
|
# unmounts any mounts active within.

# To keep the actual mount mounted, add a '/' to end
|

# $1: directory to umount
|
|
#
|
|
# Examples:
|
|
# To kill all processes and mounts within 'chroot-jessie' but keep
|
|
# 'chroot-jessie' mounted:
|
|
#
|
|
# ./umount_kill.sh chroot-jessie/
|

#
|
|
# To kill all processes and mounts within 'chroot-jessie' AND also
|
|
# umount 'chroot-jessie' mount:

# ./umount_kill.sh chroot-jessie
