# Sample init script to start an additional syslog-ng daemon.
#
# Should be installed as e.g. /etc/init.d/syslog-ng-user for
# a configuration file /etc/syslog-ng/syslog-ng-user.conf,
# where the 'user' suffix is configureable.

# Default-Start:  2 3 5
# Default-Stop:   0 1 6
# Description:    Start additional system logging daemon

# 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.
