The patch at
http://www.Leidinger.net/FreeBSD/current-patches/obsolete_removal.diff
is scheduled to be committed at Saturday or Sunday. I've the approval
of my mentor since some weeks but the code freeze for 6.0 jumped into
my way. re_at_ had some issues with it, I've changed some things, and now
I have time and no freeze in my way. :-)

The patch provides update UPDATING instructions and documentation in
the build(7) man-page. In short: "make delete-old delete-old-libs"
in /usr/src. Nothing gets deleted without your approval (except you
read the docs and provide the right magic spell)!

Notes:
* The list of files/libs/dirs is static and I hadn't time to add
  the "new old libs". I will build a new world tomorrow and add those
  libs before I commit the patch.
* Everyone who wants to come up with a different way of storing the
  list of files or adopting the NetBSD way (mtree): forget about it, I
  had this discussion several times and the commit log will contain the
  reasons why the current implementation is better.

Bye,
Alexander.
