Convert mountd to nmount(). Remove some hardcoded dependencies
on ufs, cd9660, msdosfs, and ntfs, but not all dependencies.

Use pidfile(3) in mountd(8). There is no need to use /var/run/mountd.lock
anymore.

Rename the 'log' variable rather than -fno-builtin-log

Use -fno-builtin-log. Fix svc_sendreply() missing required casts.
It is now WARNS=2 clean again.

style.Makefile(5)

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

Remove vestiges of MFS.

$Id$ -> $FreeBSD$

Removed definition of _NEW_VFSCONF. The new vfsconf interface is now
the default.

Merge from Lite2 (use new getvfsbyname() and mount(2) interface, cleanup)

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.

Automatically load NFS and a bevy of other filesystems.

Delete obsolete references to librpc.a.

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.
