### BEGIN INIT INFO
# Provides: mip6d
# Required-Start: $syslog $remote_fs
# Should-Start: $time
# Required-Stop: $syslog $remote_fs
# Should-Stop: $null
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Short-Description: MIPL - Mobile IPv6 for Linux Daemon
# Description: Start Mobile IPv6 for Linux Daemon
### END INIT INFO
# Shell functions sourced from /etc/rc.status:
# rc_check check and set local and overall rc status
# rc_status check and set local and overall rc status
# rc_status -v be verbose in local rc status and clear it afterwards
# rc_status -v -r ditto and clear both the local and overall rc status
# rc_status -s display "skipped" and exit with status 3
# rc_status -u display "unused" and exit with status 3
# rc_failed set local and overall rc status to failed
# rc_failed <num> set local and overall rc status to <num>
# rc_reset clear both the local and overall rc status
# rc_exit exit appropriate to overall rc status
# rc_active checks whether a service is activated by symlinks
. /etc/rc.status
# Reset status of this service
rc_reset
# Return values acc. to LSB for all commands but status:
# 0 - success
# 1 - generic or unspecified error
# 2 - invalid or excess argument(s)
# 3 - unimplemented feature (e.g. "reload")
# 4 - user had insufficient privileges
# 5 - program is not installed
# 6 - program is not configured
# 7 - program is not running
# 8--199 - reserved (8--99 LSB, 100--149 distrib, 150--199 appl)
#
# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signaling is not supported) are
# considered a success.
# Check for missing binaries (stale symlinks should not happen)
# Note: Special treatment of stop for LSB conformance
