# PROVIDE: carbon
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf.local or /etc/rc.conf
# to enable this service:
#
# carbon_enable (bool): Set to NO by default.
# Set it to YES to enable it.
# carbon_as_relay (bool): Set to NO by default (start cache).
# Set it to YES to run as RELAY.
# carbon_instances: Empty by default (start single instance).
# Space-separated list of instances to start.
# carbon_conf: File where carbon configuration resides
# Default: %%PREFIX%%/etc/carbon/carbon.conf
# carbon_relay_rules: File where carbon relay rules resides
# Default: %%PREFIX%%/etc/carbon/relay-rules.conf
# carbon_user: The user account carbon daemon runs as what
# you want it to be. It uses 'root' user by
# default.
# carbon_group: The group account carbon daemon runs as what
# you want it to be. It uses 'wheel' group by
# default.
# carbon_debug: Determines if you want carbon to run in debug
# mode, it may be very verbose. It will not run
# in debug by default.
# carbon_logdir: Directory where carbon logs are stored.
# Default: /var/db/carbon/log
