# This script must be executed with parameter "--start" at the end of distro shutdown
|
|
# What it does is it executes as init (process 1) and unmounts all filesystems
|
|
# including union and the USB device (if any), so it can be cleanly removed
|
|
#
|
|
# Simply add the following as the last command executed by init on your distro
|
|
# instead of the actual poweroff or shutdown command:
|
|
#
|
|
# /mnt/live/lib/cleanup --start poweroff
|
|
# or
|
|
# /mnt/live/lib/cleanup --start shutdown
|
|
#
|
|
# on Slackware, add this to rc.0:
|
|
# /mnt/live/lib/cleanup --start /sbin/$command
|
|
#
|
|
|
|
if [ "$1" = "--start" ]; then
|
|
# this is our first call. We will setup everything so the actual init actually
|
|
# reloads, but calls this script again instead of itself
