Refactor the root mount hold code and add the wait to etc/rc.d/fsck.
This fixes mounting (non-root) USB drives on boot with fsck enabled
(with non-zero 'Pass#' field in fstab(5)).

- Add descriptions to most of the rc scripts. Those are mostly taken from their
daemon's manpage and probably improved.
- Consistently use "filesystem" not "file system".

Fix the code to retry mount attempt in mountcritlocal if there are
any root mount holds. The previous one used a wrong conditional - the
"err=$?" assignment resets "$?" to 0.

After r290196, the kernel won't wait for stuff like gmirror nodes
if they are not required for mounting rootfs. However, it's possible
that some setups try to mount them in mountcritlocal (ie from fstab).

Export the list of current root mount holds using a new sysctl,
vfs.root_mount_hold, and make mountcritlocal retry if "mount -a" fails
and the list is not empty.

Add a sync to the shutdown step. In the common case this will be harmless
at worst. On a heavily loaded server it will give the fs a chance to do
its business without the axe hanging over its head.

This change does the following for the scripts that run up through
FILESYSTEMS (the default early_late_divider):
1. Move sysctl to run first
2. Move as many BEFOREs to REQUIREs as possible.
3. Minor effect, move hostid_save from right before mdconfig to right
after.

A lot of the early scripts make use of sysctl one way or another so
running this first makes a lot of sense given that system-critical
values are often placed in sysctl.conf.

My original purpose for working on this was that while doing some
debugging on other stuff I noticed that the order of execution was
different in the first pass through the early scripts and the second.
In practice that doesn't matter because the scripts are not executed the
second time. However this _can_ result in problems if the difference in
the rcorder moves a script from the late section to the early section in
the second pass (which would mean the script would not get executed).
So, I wanted to make the order of execution of the scripts in the early
section more deterministic.

In the course of debugging the ordering problems I noticed that moving
the BEFOREs to REQUIREs prevented the changes in order from the first
pass to the second pass without having to make any substantial changes.
(Of course it's no secret that I think BEFORE should be avoided as much
as possible, but this is a good example of why.)

In regards to the "Starting foo:" type messages at boot time, create and
employ a more generic solution, and use it in the individual rc.d scripts
that also have an $rc_quiet test:

1. Add check_startmsgs() to rc.subr.
2. In the rc.d scripts that use rc_quiet (and rc.subr) substitute
variations of [ -z "$rc_quiet" ] with check_startmsgs
3. In savecore add a trailing '.' to the end of the message to make it
more consistent with other scripts.
4. In newsyslog remove a : before the terminal '.' since we do not expect
there to be anything printed out in between to make it more consistent.
5. In the following scripts change "quotes" to 'quotes' where no variables
exist in the message: savecore pf newsyslog
6. In the following scripts substitute if/then/fi for the simpler (and
more consistent) check_startmsgs &&: faith stf
7. In the following scripts separate the "Starting foo:" from the terminal
'.' to make them more consistent: moused hostname pf
8. In nfsclient move the message to its own line to avoid a style bug
9. In pf rc_quiet does not apply to the _stop method, so remove the
test there.
10. In motd add 'quotes' around the terminal '.' for consistency

There's no need to announce that we're mounting local filesystems when
running in quiet mode since if we fail to mount any of them the boot
process gets interrupted.

The check for errors from the mount command did not work as intended
because another command (echo) is executed between the mount command
and the check.

Remove $NetBSD$ CVS tags. We no longer attempt to synch our rc.d files
with theirs, so this information doesn't need to be in the live file.
Having it in our CVS history is enough.

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.

Teach mount(8) about a 'late' keyword, which means the file system should
not be mounted unless the -l flag was specified.

Add an rc script, mountlate, which basically runs 'mount -a -l'. It runs
after DAEMON but before LOGIN.

This is useful for things like loopback mounts, because mountcritremote
runs before mountd / nfsd (since /usr might be a remote file system), so
an attempt to mount a loopback network file system in mountcritremote will
fail.

Also add a progress message to mountcritlocal, for the sake of symmetry
with similar messages in mountcritremote and mountlate.

Luke Mewburn has indicated that they (NetBSD) are not interested
in keeping the scripts under rc.d in sync with us. So, remove
NetBSD specific stuff (which made our scripts more complicated
than necessary).

The NetBSD ident string will be left intact, both for history and
also incase we wish to pull in future versions.

Backout ataraid rcng script. I must have missed ar0 in my scan of /dev
after my first reboot because sure enough, I'm seeing it there now and
ata(4) is doing the right thing(TM).

Pointed out by: des

Add a script that allows software RAID sets to be created before file
systems are mounted. An example set of entries for /etc/rc.conf:

ataraid_enable="YES"
ataraid_devices="ar0"
ataraid_ar0_set="ad2 ad3"
ataraid_ar0_type="RAID1"

Because there is no "correct" way of doing ATA raid (ie, geom vs.
atacontrol vs. vinum) that is bikeshed proof, this rcng script stays within
the bounds of atacontrol and assumes that other RAID solutions for GEOM or
vinum will end up in a different rcNG script.

If rc.d/mountcritlocal is unable to mount local filesystems,
then immediately terminate the shell (during boot this
also terminates the parent rc(8) shell). This was the pre-rcNG behaviour.

Also, remove an extraneous mount /.

PR: conf/57659
Submitted by: yar (with modifications)

Move networkfs_types from mountcritlocal into defaults/rc.conf as netfs_types.
Also add logic into mountcritremote to add extra_netfs_types to the list.

This unbreaks putting smbfs, portalfs and now nwfs in fstab.

nwfs is network filesystem. Treat it as such when mounting filesystems.

Convert from `${CMD_OSTYPE}` to ${OSTYPE}. This saves a shell invocation on
OS-dependent case switches.
