d7c5bf81cb Move the diagnostic output when the rc.subr(8) glue automatically starts a
service behind $rc_quiet. Instead, output a warning if the pre-command
routine or the command itself failed. Arguably, it's more useful to know when
a command failed to start than it is to have an endless list of
"Starting ...." lines[1].

[1] - This change actually helped me to discover a bug in rc.d/{lockd,statd}
      (fixed in r179941) that used to fail silently before.

a850398f3b Re-implement: do not silently fail when a command is not carried
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.

581487018d Backout previous commit. It's going to clutter the console
during boot and shutdown. I think I'll hide it behind autoboot or
maybe take brooks@ suggestion and implement a different command
prefix for booting/shutdown purposes, but in any case it needs more
thought and attention.

039e8df3cf Be robust to a bogus script specification or contents
when figuring out what the real interpreter is for an
interpreted command.  That is, check whether we can read
the script file in the first place and, if so, make sure

3d03791bb4 o Implement the stop_boot subroutine [1]. This subroutine can be used by
scripts in rc.d to stop rc(8) from booting into multi-user mode when
  a critical or severe error condition is encountered.

o Modify scripts in etc/rc.d that already implemented this functionality
  independently.

o Document it.

[1] - This subroutine was implemented in FreeBSD in rc.d/fsck. I moved it
      to rc.subr(8). Our version differs slightly in that it takes an
      optional argument to stop the boot even if "autoboot" is not set.

b5af060613 Prepend ${_chroot} to a pathname in a consistent and robust way:
insert a slash between ${_chroot} and the pathname if and only if
${_chroot} is set to a non-empty string.  Now the pathname is very
likely to be absolute, but we shouldn't take that for granted.

c7be7e20f6 Allow for /usr/bin/env when parsing the shebang line from an
interpreted $command.  Some "portable" sofware packages use such a
line to skip the task of figuring out the absolute pathname of the
interpreter at install time, e.g.:

	#!/usr/bin/env python

It is insecure, but a popular book on Python seems to have advised
it to a wide audience.  Hence a number of such scripts in the ports,
mostly written in Python.

c89572720c MFp4:
Implement the checks for required_* objects as two functions, one
to be run before precmd and the other after it.  They get the current
rc command as an argument so they can choose what requirement tests
to perform.  As of now, only "start" needs such tests.

Implement a new requirement variable, required_modules.  It can
list kernel modules that need to be loaded after start_precmd
indicated success.  Each name in the list can be just "file", or
"file:module", or "file~regex".  This will allow us to remove a lot
of duplicated code from rc.d scripts.

Perform the checks not only for the default start method, but for
any method.  This allows for more flexibility and fixes a few rc.d
scripts (namely newsyslog, pf, sendmail) that rely on a required_*
variable while providing a non-default start method.

To be able to call the new check_required* functions naturally,
remove lots of crufty duplicated code pieces from run_rc_command
and replace each of them by a call to the helper function providing
a single corrected instance of the respective code snippet.  Now
run_rc_command isn't as scary as it used to be, and it even appears
to have quite a nice logic that was obscured by the old crufty code.

In the default handler for restart, run start from a subshell to
protect global varibles, e.g., _postcmd, from modification by the
start handler.  This enables using restart_postcmd. [x]

Yaroslav Tykhiy
a9a6b38f96 The ps(1) command is unfriendly to scripts by default because
it limits the width of its output to the value of $COLUMNS, or
what TIOCGWINSZ reports, or 79 columns.  We should specify -ww
to ps(1) so that it removes the limit and prints lines in full.
Otherwise very long command pathnames could be mishandled, e.g.,
by _find_processes().

1679c7f4f4 Quite a number of rc.d scripts try to load kernel modules. Many
of them do that conditionally depending on kldstat.  The code is
duplicated all over, but bugs can be uniqie.

To make the things more consistent, introduce a new rc.subr function,
load_kld, which takes care of loading a kernel module conditionally.

01b19d7852 Add two new scripts (mdconfig/mdconfig2) to replace old ramdisk{,-own}
scripts. These scripts handle vnode backed md(4) devices.

Old ramdisk{,-own} scripts will stay a bit in CVS to allow some time for
migration since variable names have changed (ramdisk_* -> mdconfig_*).

Two new variables have been introduced to be able to populate the md(4)
device once it has been mounted (mdconfig_*_files and mdconfig_*_cmd).

Use should be as easy as:

mdconfig_md0="-t malloc -s 10m"
mdconfig_md1="-t vnode -f /var/foo.img"

See rc.conf(5) for more information and description of the additional
variables.

b37ccb58ef Change how *.sh scripts are handled. If the script is in /etc/rc.d,
source it into the shell. If not, handle it in a subshell the same
way that "real" rc.d-style scripts are handled. This will dramatically
ease the "process local scripts in the base rcorder" transition.

0f3ce2b32c Introduce startup scripts from the local_startup directories to
the base rcorder. This is accomplished by running rcorder twice,
first to get all the disks mounted (through mountcritremote),
then again to include the local_startup directories.

This dramatically changes the behavior of rc.d/localpkg, as
all "local" scripts that have the new rc.d semantics are now
run in the base rcorder, so only scripts that have not been
converted yet will run in rc.d/localpkg.

Make a similar change in rc.shutdown, and add some functions in
rc.subr to support these changes.

Bump __FreeBSD_version to reflect this change.
