16511f59a9 Remove doubtful structure definition with variable array members.
I believe this is not a valid C99 construct.  Use directly calculated
offsets into the supplied buffer, using specified members length,
to fill appropriate structure.

Either use sysctl, or copy the value of the UNAME_x environment
variable, instead of unconditionally doing sysctl, and then
overriding a returned value with user-specified one.

c26efd485e Switch BUILD_ARCH in Makefile to use uname -p suggested by ru.
Switch strncpy to strlcpy suggested by gad and issue found by pjd.
Add to uname(3) man page describing:
	UNAME_s
	UNAME_r
	UNAME_v
	UNAME_m
Add to getosreldate(3) man page describing:
	OSVERSION

d630a05f40 Add support to easily build FreeBSD unpacked in a chroot of another
FreeBSD machine.  To do this add the man 1 uname changes to __xuname.c
so we can override the settings it reports.  Add OSVERSION override
to getosreldate.  Finally which Makefile.inc1 to use uname -m instead
of  sysctl -n hw.machine_arch to get the arch. type.

With these change you can put a complete FreeBSD OS image into a
chroot set:
	UNAME_s=FreeBSD
	UNAME_r=4.7-RELEASE
	UNAME_v="FreeBSD $UNAME_r #1: Fri Jul 22 20:32:52 PDT 2005 fake@fake:/usr/obj/usr/src/sys/FAKE"
	UNAME_m=i386
	UNAME_p=i386
	OSVERSION=470000
on an amd64 or i386 and it just work including building ports and using
pkg_add -r etc.  The caveat for this example is that these patches
have to be applied to FreeBSD 4.7 and the uname(1) changes need to
be merged.  This also addresses issue with libtool.

This is usefull for when a build machine has been trashed for an
old release and we want to do a build on a new machine that FreeBSD
4.7 won't run on ...

32e479705a This is kind of a hack, but it should work. Currently, world is broken
because libc/rpc/key_call.c references uname(), and ps/print.c also
defines uname(), and ps is linked statically.  This leads to a symbol
clash.  The userland uname(3) kinda sucked anyway as the hostname
etc was too short.  And since the libc rpc interface now uses
the utsname.nodename which gets truncated, I was tempted into doing
something about it.  Create a new userland uname function, called
__xuname() which takes an extra argument that allows you to change
the size of the fields.  uname() becomes a static inline function
in sys/utsname.h that passes the extra argument in.  struct utsname
has its field members expanded by default now in userland.
We still provide a 'uname' externally linkable function for things
that either think that they ``know'' the utsname format and assume
32 character strings and bypass the include file, or objects that
are linked against old libcs.  ie: just about every plausible
case that I can think of is covered.  Should we ever change the
default lengths again, a libc major bump should not be required
as the size is now passed to the function.

XXX the uname(2) in the kernel is for FreeBSD 1.1 binary compatability!
All the uname(3) functions that are exported to userland are actually
implemented in libc with sysctl.  uname(1) uses sysctl directly and
does not call uname(3).

1130b656e5 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.

b938dc2407 sysctl(3) can return an error (setting errno to ENOMEM) when the
fields in the utsname structure are too small to hold their
corresponding MIB variables.  Don't return an error in this case.
