out because the rc.conf(5) variable was not enabled. Display a message that the command wasn't run and offer suggestions on what the user can do. Implement a quiet prefix, which will disable some diagnostics. The fast prefix also implies quiet. During boot we use either fast or quiet. For shutdown we already use 'faststop'. So, this informational message should only appear during interactive use. An additional benefit of having a quiet prefix is that we can start putting some of our diagnostic messages behind this knob and start "de-cluttering" the console during boot and shutdown.

|
|
#
|
|
# extra_commands n List of extra commands supported.
|
|
#
|
|
# pidfile n If set, use check_pidfile $pidfile $command,

|
|
# In either case, only check if $command is set.
|
|
#
|
|

|
#
|
|
# ${name}_groups n Comma separated list of supplementary groups
|
|
# to run the chrooted ${command} with.
|
|
# Requires /usr to be mounted.
|
|
#
|
|
# ${rc_arg}_cmd n If set, use this as the method when invoked;

|
# operation (i.e, after checking for required
|
|
# bits and process (non)existence).
|

#
|
|
# ${rc_arg}_postcmd n If set, run just after performing the

# files before running a (re)start command.
|
|
#
|
|
# required_modules n If set, ensure the given kernel modules are
|

# loaded before running a (re)start command.
|
|
# The check and possible loads are actually
|
|
