### BEGIN INIT INFO
# Provides:          atftpd
# Required-Start:    $syslog $remote_fs
# Required-Stop:     $syslog $remote_fs
# Default-Start:     3 5
# Default-Stop:      0 1 2 6
# Short-Description: launch atftpd server
# Description:       launch Advanced TFTP Server
### 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_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
. /etc/rc.status
# First 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 - 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.
