### BEGIN INIT INFO
# Provides: stunnel
# Required-Start: $local_fs $remote_fs
# Required-Stop: $local_fs $remote_fs
# Should-Start: $syslog
# Should-Stop: $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start or stop stunnel 4.x (TLS tunnel for network daemons)
# Description: Starts or stops all configured TLS network tunnels. Each *.conf file in
# @sysconfdir@/stunnel/ will spawn a separate stunnel process. The list of files
# can be overridden in @sysconfdir@/default/stunnel, and that same file can be used
# to completely disable *all* tunnels.
### END INIT INFO
# Author / upstream maintainer note:
# With the planned introduction of a control interface (conceptually similar to
# apache2ctl), running separate processes for each *.conf will become obsolete.
# Please add "include = @sysconfdir@/stunnel/conf.d" to stunnel.conf instead.
