MFC r230099:

Change rcvar= assignments to the literal values set_rcvar
would have returned. This will slightly reduce boot time,
and help in diff reduction to HEAD.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

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.

FILESYSTEMS requires root, so requiring both of them is redundant.

Add a dummy script, FILESYSTEMS, which depends on root and mountcritlocal
and takes over mountcritlocal's role as the early / late divider. This
makes it far easier to add rc scripts which need to run early, such as a
startup script for zfs, which is right around the corner.

This change should be a no-op; I have verified that the only change in
rcorder's output is the insertion of FILESYSTEMS immediately after
mountcritlocal.

The 'reload' command did the same as 'restart' command.
Allow user to decide if SAD and SPD entries should be flushed on 'reload'.
With this change flush/spdflush is not done automatically (it could still
be done from ipsec.conf).

Remove stale comment.

This change should be made in rev1.9.

Use $ipsec_file instead of hardcoded /etc/ipsec.conf.

This change should be made in rev1.2.

First start rc.d/ipsec and then rc.d/mountcritremote, so we can mount
NFS file system over IPsec.

Suggested by: Tomasz Pi³at <tomasz.pilat@axelspringer.pl>

setkey(8) was repo-copied from usr.sbin/ to sbin/.
This will allow for NFS mount of /usr over IPsec.

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

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

Remove scripts we don't use from requirement lines. These were
hold-overs from the initial NetBSD import.

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.

tty whacking should occur early, but not so early that the
required commands are not on a mounted file system.

We stopped reloading rc.conf for each script a long time ago. Things
shouldn't depend on that any more.

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

FreeBSD has setkey in different location from NetBSD.

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.
