install them.

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

This simplifies pathing in make/displayed output.

Consistently set RPCGEN_CPP when running rpcgen, so the C preprocessor
set via ${CPP} is used, instead of always using hardcoded /usr/bin/cpp.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

The last big commit: let usr.sbin/ use WARNS=6 by default.

- Import the HEAD csup code which is the basis for the cvsmode work.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

$Id$ -> $FreeBSD$

Fixed missing dependencies on headers generated by rpcgen, as usual.
Removed bogus dependencies of generated .c files on generated headers.
Sorted sources lists.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

yppush_main.c:

- Remove unused 'pid' member from the jobs structure. (This was left over
from an earlier incarnation of the program that used multiple processes.)

- Remove #ifdef'ed longjmp() stuff.

- Print warning message if the 'pushing' host is not the master for
a map being pushed but don't bail out. (While yppush should only
be used on an NIS master, using it elsewhere is not an unpardonable sin.)

yppush.8:

- Fix a couple of mind-os.

Makefile

- Change format to hopefully ease bootstrapping. (Suggested by wollman.)
Other Makefiles should follow.

This commit was manufactured by cvs2svn to create branch 'WPAUL'.

Import the new yppush.

This program does what the old one did, PLUS:

- Supports parallel jobs (like the SunOS yppush)
- Does everything in one proces instead of fork()ing off
children processes as callback listeners (this is done
using async socket I/O).
- Can be used to transmit maps to user-specified hosts.
- Has a much more verbose verbose option.
- Reuses existing code from ypserv and ypxfr.
- Uses some rpcgen-erated code as well.
- Isn't fattening. :)

Note that this is going in /usr/sbin rather than /usr/bin like
the old one. yppush is an administrative command it it's anything.
