- Add vnode-backed swap space specification support. This is enabled when
device names "md" or "md[0-9]*" and a "file" option are specified in
/etc/fstab like this:

md none swap sw,file=/swap.bin 0 0

- Add GBDE/GELI encrypted swap space specification support, which
rc.d/encswap supported. The /etc/fstab lines are like the following:

/dev/ada1p1.bde none swap sw 0 0
/dev/ada1p2.eli none swap sw 0 0

.eli devices accepts aalgo, ealgo, keylen, and sectorsize as options.

swapctl(8) can understand an encrypted device in the command line
like this:

# swapctl -a /dev/ada2p1.bde

- "-L" flag is added to support "late" option to defer swapon until
rc.d/mountlate runs.

- rc.d script change:

rc.d/encswap -> removed
rc.d/addswap -> just display a warning message if $swapfile is defined
rc.d/swap1 -> renamed to rc.d/swap
rc.d/swaplate -> newly added to support "late" option

These changes alleviate a race condition between device creation/removal
and swapon/swapoff.

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

rc.d/fsck: allow additional options for fsck_y_enable via fsck_y_flags

Primary intention is to allow to pass -C option to avoid (re-)checking
clean filesystems when preening fails and fsck -y kicks in.

Move a lot of diagnostic output behind $rc_quiet in scripts that
implement their own start command.

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.

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

Discussed with: dougb, brooks

Don't run fsck if there's no /etc/fstab.

In particular, this allows a "virgin" system installed from
source (installworld, installkernel, cd etc && make distribution)
to boot correctly and modestly simplifies the creation
of single-partition network/cdrom/CF bootable images.

Mark scripts as not usable inside a jail by adding keyword 'nojail'.

Some suggestions from: rwatson, Ruben de Groot <mail25@bzerk.org>

Remove an extraneous semicolon (;;).

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.

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

Fix style bugs:
* Space -> tabs conversion.
* Removed blanks before semicolon in "if ... ; then".
* Proper indentation of misindented lines.
* Put a full stop after some comments.
* Removed whitespace at end of line.

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

Merge in all the changes that Mike Makonnen has been maintaining for a

Import the NetBSD 1.5 RC system.

Note that `rc' and `rc.shutdown' could not be imported because we already
have files with those names.
