# rc.lxc init script
# Written by Matteo Bernardini <ponce@slackbuilds.org>
#
# This script checks for the presence of the parameter lxc.start.auto
# in the available container configurations: if it's set to 1 the
# container is started (in an auto-detached screen session if
# screen is available) when rc.lxc is called with the "start" param.
#
# To stop the container it uses lxc-attach to execute /sbin/halt
# inside of it.
