mount. It is possible to have v3 MOUNT but only v2 NFS, for instance for
a custom user-mode server like CFS.

a reserved port, so why not the nfs rpc's themselves?
With user allowed mounts, this perhaps needs a closer look, but
on the other hand, a user could already specify the flag.
If normal users should not be able to use resserved ports, the kernel
should check for the flag at mount time.
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.
for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.
mount_* programs. While we're at it, collapse the four now-identical
mount programs for devfs, fdesc, kernfs, and procfs into links to
a new mount_std(8) which can mount any really generic filesystem
such as these when called with the appropriate argv[0].
Also, convert the mount programs to use sysexits.h.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server. It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.
Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs. Servers will need to build and
install /usr/sbin/mountd.
NFS diskless support is untested.

most common cd9660 and nfs options like God intended them. (It is now
possible to say
mount -o ro,soft,bg,intr there:/foo/bar /foo/bar
again.) This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3). Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.
(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)
Also moved some KERBEROS related stuff inside the #ifdef.
Should we always try to do a reverse lookup (IP#->name) ?
It has som merit, but is probably against the tradition or huh ?
