### BEGIN INIT INFO
# Provides:                   acpid
# Required-Start:             $local_fs
# Required-Stop:              $null
# Default-Start:              2 3 5
# Default-Stop:               0 1 6
# Short-Description: Listen and dispatch ACPI events from the kernel
# Description:       acpid reads events from /proc/acpi/event and dispatches
#	them (by SuSE default) to other "users" like powersaved, HAL and IAL.
#	Actions for those events are (by SUSE default) configured in the
#	powersaved configuration.
#	Additionally this start script loads all needed modules.
### 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     ditto but be verbose in local rc status
#      rc_status -v -r  ditto and clear the local 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 local rc status (overall remains)
#      rc_exit          exit appropriate to overall rc status
#      rc_active	checks whether a service is activated by symlinks
#      rc_splash arg    sets the boot splash screen to arg (if active)

# 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.
