### BEGIN INIT INFO
# Provides: FOO
# Required-Start: $remote_fs $syslog
# Required-Stop:  $remote_fs $syslog
# Default-Start:  3 5
# Default-Stop:   0 1 2 6
# Description:    Start FOO to allow XY and provide YZ
#	continued on second line by '#<TAB>'
### 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.

# Source SuSE config (if still necessary, most info has been moved)

# 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     ditto but be verbose in local rc status
#      rc_status -v -r  ditto and clear the local rc status
#      rc_failed        set local and overall rc status to failed
#      rc_failed <num>  set local and overall rc status to <num><num>
#      rc_reset         clear local rc status (overall remains)
#      rc_exit          exit appropriate to overall rc status
#      rc_active	checks whether a service is activated by symlinks

# 0 - success
# 1 - generic or unspecified error

# 3 - unimplemented feature (e.g. "reload")
# 4 - insufficient privilege
# 5 - program is not installed
# 6 - program is not configured
# 7 - program is not running
#
# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signalling is not supported) are
# considered a success.
