### BEGIN INIT INFO
# Provides: xl2tpd
# Required-Start: $syslog $remote_fs
# Required-Stop:  $syslog $remote_fs
# Default-Start:  3 5
# Default-Stop:   0 1 2 6
# Short-Description: Start xl2tpd (to provide L2TP VPN's)
# Description:    Start xl2tpd to provide L2TP VPN tunnels
#	normally used with IPsec (openswan)
### END INIT INFO

# Note on Required-Start: It does specify the init script ordering,
# not real dependencies. Depencies have to be handled by admin
# resp. the configuration tools (s)he uses.
