351 # Name Needed Purpose
352 # ---- ------ -------
353 # name y Name of script.
355 # command n Full path to command.
356 # Not needed if ${rc_arg}_cmd is set for
359 # command_args n Optional args/shell directives for command.
361 # command_interpreter n If not empty, command is interpreted, so
362 # call check_{pidfile,process}() appropriately.
364 # extra_commands n List of extra commands supported.
366 # pidfile n If set, use check_pidfile $pidfile $command,
367 # otherwise use check_process $command.
368 # In either case, only check if $command is set.
370 # procname n Process name to check for instead of $command.
372 # rcvar n This is checked with checkyesno to determine
373 # if the action should be run.
375 # ${name}_program n Full path to command.
376 # Meant to be used in /etc/rc.conf to override
379 # ${name}_chroot n Directory to chroot to before running ${command}
380 # Requires /usr to be mounted.
382 # ${name}_chdir n Directory to cd to before running ${command}
383 # (if not using ${name}_chroot).
385 # ${name}_flags n Arguments to call ${command} with.
386 # NOTE: $flags from the parent environment
387 # can be used to override this.
389 # ${name}_nice n Nice level to run ${command} at.
391 # ${name}_user n User to run ${command} as, using su(1) if not
392 # using ${name}_chroot.
393 # Requires /usr to be mounted.
395 # ${name}_group n Group to run chrooted ${command} as.
396 # Requires /usr to be mounted.
398 # ${name}_groups n Comma separated list of supplementary groups
399 # to run the chrooted ${command} with.
400 # Requires /usr to be mounted.
402 # ${rc_arg}_cmd n If set, use this as the method when invoked;
403 # Otherwise, use default command (see below)
405 # ${rc_arg}_precmd n If set, run just before performing the
406 # ${rc_arg}_cmd method in the default
407 # operation (i.e, after checking for required
408 # bits and process (non)existence).
409 # If this completes with a non-zero exit code,
410 # don't run ${rc_arg}_cmd.
412 # ${rc_arg}_postcmd n If set, run just after performing the
413 # ${rc_arg}_cmd method, if that method
414 # returned a zero exit code.
416 # required_dirs n If set, check for the existence of the given
417 # directories before running a (re)start command.
419 # required_files n If set, check for the readability of the given
420 # files before running a (re)start command.
422 # required_modules n If set, ensure the given kernel modules are
423 # loaded before running a (re)start command.
424 # The check and possible loads are actually
425 # done after start_precmd so that the modules
426 # aren't loaded in vain, should the precmd
427 # return a non-zero status to indicate a error.
428 # If a word in the list looks like "foo:bar",
429 # "foo" is the KLD file name and "bar" is the
430 # module name. If a word looks like "foo~bar",
431 # "foo" is the KLD file name and "bar" is a
432 # egrep(1) pattern matching the module name.
433 # Otherwise the module name is assumed to be
434 # the same as the KLD file name, which is most
435 # common. See load_kld().

438 # listed variables before running the default
441 # Default behaviour for a given argument, if no override method is
444 # Argument Default behaviour
