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.

that policies need to generated before you do this.
in and setting -kb, check it out again, since the initial check in
trashes any RCSIDs (because -kb wasn't set at that time).
This stops the annoying situation where you add a new file (e.g, "foo")
which contains an RCSID and you get *two* notifications of differences
in two successives runs of /etc/security; the first when the file is
initially checked in and a second when diff finds the RCSID is different
(contains "foo.conf,v 1.1" instead of "foo,v 1.66").
Replace $critical_filesystems with $critical_filesystems_remote .
The new names are now consistent with the type argument that
mount_critical_filesystems() is called with, and allows for other types to
be easily supported by that function.
For backwards compatibility purposes, if the now obsolete variable is defined
(even empty), it takes precedence over the new form, and you will be warned.
If you want to stop the warnings, update your rc.conf(5) settings!
make them "externally" available:
Previous Current Purpose
-------- ------- -------
_arg rc_arg Argument to command, after fast/force
processing performed (and prefix
removed)
_flags rc_flags Flags to start the default command
with. Defaults to ${name}_flags,
unless overridden by $flags from the
environment. This variable may be
changed by the precmd method.
_pid rc_pid PID of command (if appropriate).
_rc_run_fast rc_fast Not empty is "fast" was provided.
_rc_run_force rc_force Not empty is "force" was provided.
- Use rc_flags instead of _flags or ${name}_flags in various rc.d scripts,
so that $flags from the environment overrides ${name}_flags from rc.conf(5).
Fixes [bin/15800].
If set, the first line of $command is read, the leading #! is
removed, whitespace is normalised, the first word is checked
against $command_interpreter, and the result is used as the
string to match in the ps(1) output.
This code isn't infallable, but works for common cases such as
#!/bin/sh
#! /usr/pkg/bin/perl -w
This helps solve the problem described in [bin/15563], and by
Ed Ravin on tech-userlevel.
- Move the common elements of check_process() and check_pidfile() into
_find_processes(), and call appropriately.
