- 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".

Approved by: bapt, brueffer
Differential Revision: D452

- 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.

Backout previous commit due to PEBKAC

When swap resides on a mirror and it is not stopped, the mirror
is degraded upon the next reboot and will have to be rebuild.
Thus call swapoff when rebooting (read: when stopping swap1)

Add a -q flag to swapon(8) to suppress informational messages. Use it in
rc.d.
Note: errors are not affected by this flag.

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.

Stop method for swap1 script was introduced, because gmirror needed it.
Now gmirror use shutdown hooks to mark mirrors as clean on shutdown,
so this is not needed anymore.

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

Discussed with: dougb, brooks
MFC after: 3 days

Teach swap1 script how to remove added swap devices on system shutdown.
Without this change, if one had a swap-on-mirror configuration, gmirror
will rebuild mirror component(s) on boot, because they are dirty (they
were open on shutdown).

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

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

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
than necessary), starting with the NetBSD KEYWORD.

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
while. This is only the script pieces, the glue for the build comes next.

This commit was generated by cvs2svn to compensate for changes in r78344,
which included commits to RCS files with non-trunk default branches.

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.
