The output without the dollar sign is less confusing as it's actual
valid shell syntax:
$ /etc/rc.d/foo rcvar
# food
food=YES
Brought up on tech-userlevel@ by Rocky Hotas with some LGTMs from
other people and no objections.
We still refer to '$food' in warnings/errors though.
Use ps -A instead of ps -ax (-A means -ax, but -A is posix, -x is not)
Use ps -o args instead of ps -o command (same reason).
This makes no difference when the ps used is /bin/ps on NetBSD, but
can make a difference when some other ps command gets invoked instead.

are still invoked by the rc system and fail.

Remove the expensive tests in _have_rc_postprocessor(), as proposed by apb@.
It more than halves the multiuser boot time on slow machines and brings
it back near to the previous level.
inline tests like [ -n "${_rc_postprocessor_fd}" ]. The new function
performs a few new tests, including verifying that /etc/rc is still
running (using a new _rc_pid variable set by /etc/rc).
This is intended to deal with the case that a script run from /etc/rc
spawns a background process, then /etc/rc exits, but the background
process still has environment variables inherited from /etc/rc.

by /etc/rc. Similarly for printf with a format that does not end with
"\n". Previously, the partial line would not be visible on the console
until a newline was printed, possibly after an annoying delay.
This is done by adding echo() and printf() shell functions to rc.subr,
so that naive use of the echo and printf commands in rc.d scripts will
call these functions instead of the underlying commands. These shell
functions send a new "nop" metadata message after the partial line, and
the rc_postprocess function in /etc/rc disentangles the partial line of
plain output from the metadata "nop".
Also add a "-n" option to the print_rc_normal function in rc.subr,
and make some cosmetic changes.
the command being executed. This is to allow rc.d scripts to do:
run_rc_command "${@}"
instead of:
run_rc_command "${1}"
and let the command handler (start, stop, etc.) receive the arguments after
the command name.
None of the default commands allow extra arguments, and they will error out
if any are given. This is mostly useful for script-specific commands that
are only supposed to be used through the command line and, therefore, need
to provide a friendly interface.
Proposed in tech-userlevel@. No major objections except for some minor
concerns regarding whether this should be allowed or not at all. Note that
I'm not touching any of the rc.d scripts in the base system, so this is
effectively a no-op from the user point of view.
in rc.subr to be marked as optional. This means that it's not an
error if the file system is not mentioned in /etc/fstab. It is
still an error if something else goes wrong.
Change the defaults for these two variables in /etc/defaults/rc.conf:
critical_filesystems_local="OPTIONAL:/var"
critical_filesystems_remote="OPTIONAL:/usr"
and which can suppress output in silent mode. Silent mode is enabled
via the new rc_silent variable, which defaults to a value that depends
on the kern.boothowto sysctl.
Part of the /etc/rc silent changes requested in PR 41946
and proposed in tech-userlevel.
When rc scripts are started from interactive shell, be nice and when user
tries to start an unconfigured service, point him to rc.conf(5) and tell
him about the one* keyword. Also be more user friendly when an unknown
argument is entered.
Example:
# /etc/rc.d/cron start
$cron is not enabled - see rc.conf(5).
Use the following if you wish to perform the operation:
/etc/rc.d/cron onestart
# /etc/rc.d/cron nonsense
/etc/rc.d/cron: unknown directive 'nonsense'.
Usage: /etc/rc.d/cron [fast|force|one](start stop restart rcvar status poll)

${rcvar}=yes yet all the other prerequisite tests are still performed.
The existing ``force'' prefix is a sledgehammer that ignores all the
prerequisite checks and always returns a zero exit status; this is a
more gentle approach to the problem of "manipulate this disabled
service without editing rc.conf(5)".
in some circumstances where run_rc_script()'s sourcing of an rc.d file
which then sourced rc.subr, the `optimisation' in rc.subr to "return as
we're already loaded" would finish more than just the inner-most sourcing.
I haven't tracked down the exact issue, but removing the `optimisation'
fixes the problem I noticed in starting up certain rc.d scripts, and
may fix [bin/22053] as well.
