    lib/libc/gen         __xuname.c getosreldate.c 
  Log:
  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 at 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 ...
