355 # command_args n Optional args/shell directives for command.
357 # command_interpreter n If not empty, command is interpreted, so

360 # extra_commands n List of extra commands supported.
362 # pidfile n If set, use check_pidfile $pidfile $command,
363 # otherwise use check_process $command.
364 # In either case, only check if $command is set.
366 # procname n Process name to check for instead of $command.
368 # rcvar n This is checked with checkyesno to determine
369 # if the action should be run.
371 # ${name}_program n Full path to command.
372 # Meant to be used in /etc/rc.conf to override
375 # ${name}_chroot n Directory to chroot to before running ${command}
376 # Requires /usr to be mounted.
378 # ${name}_chdir n Directory to cd to before running ${command}
379 # (if not using ${name}_chroot).
381 # ${name}_flags n Arguments to call ${command} with.
382 # NOTE: $flags from the parent environment
383 # can be used to override this.

388 # using ${name}_chroot.
389 # Requires /usr to be mounted.
391 # ${name}_group n Group to run chrooted ${command} as.

394 # ${name}_groups n Comma separated list of supplementary groups
395 # to run the chrooted ${command} with.
396 # Requires /usr to be mounted.
398 # ${rc_arg}_cmd n If set, use this as the method when invoked;
399 # Otherwise, use default command (see below)
401 # ${rc_arg}_precmd n If set, run just before performing the
402 # ${rc_arg}_cmd method in the default
403 # operation (i.e, after checking for required
404 # bits and process (non)existence).
405 # If this completes with a non-zero exit code,
406 # don't run ${rc_arg}_cmd.
408 # ${rc_arg}_postcmd n If set, run just after performing the
409 # ${rc_arg}_cmd method, if that method
410 # returned a zero exit code.
412 # required_dirs n If set, check for the existence of the given
413 # directories before running the default
416 # required_files n If set, check for the readability of the given
417 # files before running the default (re)start
420 # required_vars n If set, perform checkyesno on each of the
421 # listed variables before running the default
