Add SEE ALSO.

Support shadow.byname and shadow.byuid maps, protecting them by
insisting on privileged port access.

Include /var/yp/Makefile.local if it exists and suggest using
it to override /var/yp/Makefile behaviour.

mdoc(7) police: Removed redundant .Ns calls.

mdoc(7) police: tidy up the markup.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

mdoc(7) police: simplify the fix in rev. 1.25.

Fix a spacing issue. (No content changes.)

Eliminate mdocNG warnings caused by misplaced or extraneous macro calls.

Prepare for mdocNG.

mdoc(7) police: use the new features of the Nm macro.

Fix problems introduced in rev 1.18:

* Broken (sectionless) cross-reference to nsswitch.conf.
* Trailing whitespace.

Use Fx macro wherever possible.

Document passwd_format further.

Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.

Use .Tn, .Bx Free and .An.

/etc/sysconfig -> /etc/rc.conf.

Use the .Fx macro for FreeBSD references for releases prior to 2.0.
Use the .Tn macro for generic FreeBSD references. Cleanup other
formatting problems noticed while making the above changes.

Revert $FreeBSD$ back to $Id$

Fix a bunch of man pages to stop abusing the .Nm macro, along
with some other minor fixes for some problems I noticed
while making these changes.

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.

Use the .Bx macro where appropriate.

Correct some man page xrefs, and some other minor changes to bring some
man pages up to mdoc guidelines and fix some minor formatting glitches.
Also fixed a number of man pages to not abuse the .Xr macro to
display functions and path names and a lot of other junk.

Fix a bunch of spelling errors in a bunch of man pages.

Update this man page to reflect reality.

/etc/rc.netstart back to /etc/netstart

netstart -> rc.netstart

Moved YP general explanation manual page to a slightly more appropriate
location.
