388 # ---- ------ -------
389 # name y Name of script.
391 # command n Full path to command.
392 # Not needed if ${rc_arg}_cmd is set for
395 # command_args n Optional args/shell directives for command.
397 # command_interpreter n If not empty, command is interpreted, so
398 # call check_{pidfile,process}() appropriately.
400 # extra_commands n List of extra commands supported.
402 # pidfile n If set, use check_pidfile $pidfile $command,
403 # otherwise use check_process $command.
404 # In either case, only check if $command is set.
406 # procname n Process name to check for instead of $command.
408 # rcvar n This is checked with checkyesno to determine
409 # if the action should be run.
411 # ${name}_program n Full path to command.
412 # Meant to be used in /etc/rc.conf to override
415 # ${name}_chroot n Directory to chroot to before running ${command}
416 # Requires /usr to be mounted.
418 # ${name}_chdir n Directory to cd to before running ${command}
419 # (if not using ${name}_chroot).
421 # ${name}_flags n Arguments to call ${command} with.
422 # NOTE: $flags from the parent environment
423 # can be used to override this.
425 # ${name}_nice n Nice level to run ${command} at.
427 # ${name}_user n User to run ${command} as, using su(1) if not
428 # using ${name}_chroot.
429 # Requires /usr to be mounted.
431 # ${name}_group n Group to run chrooted ${command} as.
432 # Requires /usr to be mounted.
434 # ${name}_groups n Comma separated list of supplementary groups
435 # to run the chrooted ${command} with.
436 # Requires /usr to be mounted.
438 # ${rc_arg}_cmd n If set, use this as the method when invoked;
439 # Otherwise, use default command (see below)
441 # ${rc_arg}_precmd n If set, run just before performing the
442 # ${rc_arg}_cmd method in the default
443 # operation (i.e, after checking for required
444 # bits and process (non)existence).
445 # If this completes with a non-zero exit code,
446 # don't run ${rc_arg}_cmd.
448 # ${rc_arg}_postcmd n If set, run just after performing the
449 # ${rc_arg}_cmd method, if that method
450 # returned a zero exit code.
452 # required_dirs n If set, check for the existence of the given
453 # directories before running a (re)start command.
455 # required_files n If set, check for the readability of the given
456 # files before running a (re)start command.
458 # required_modules n If set, ensure the given kernel modules are
459 # loaded before running a (re)start command.
460 # The check and possible loads are actually
461 # done after start_precmd so that the modules
462 # aren't loaded in vain, should the precmd
463 # return a non-zero status to indicate a error.
464 # If a word in the list looks like "foo:bar",
465 # "foo" is the KLD file name and "bar" is the
466 # module name. If a word looks like "foo~bar",
467 # "foo" is the KLD file name and "bar" is a
468 # egrep(1) pattern matching the module name.
469 # Otherwise the module name is assumed to be
470 # the same as the KLD file name, which is most
471 # common. See load_kld().

474 # listed variables before running the default
477 # Default behaviour for a given argument, if no override method is
480 # Argument Default behaviour
