363 # Requires /usr to be mounted.

366 # (if not using ${name}_chroot).

370 # can be used to override this.

382 # to run the chrooted ${command} with.

389 # ${rc_arg}_cmd method in the default
390 # operation (i.e, after checking for required
391 # bits and process (non)existence).
392 # If this completes with a non-zero exit code,

395 # ${rc_arg}_postcmd n If set, run just after performing the
396 # ${rc_arg}_cmd method, if that method
397 # returned a zero exit code.
399 # required_dirs n If set, check for the existence of the given
400 # directories before running the default
403 # required_files n If set, check for the readability of the given
404 # files before running the default (re)start
407 # required_vars n If set, perform checkyesno on each of the
