I'm using WITHOUT_CTM and WITHOUT_CVS. When building the new system, cvs and
ctm* are _not_ built. But the old executables are not deleted; look at their
dates. According to src.conf(5):

	"The only purpose of src.conf is to control the compilation of
	 the FreeBSD source code..." 

So the fact that old executables and manual pages are not deleted is not
strictly a bug.

Using "make delete-old" includes /usr/src/ObsoleteFiles.inc into the build
Makefile. This file contains the names of files that have been made obsolete
by newer FreeBSD versions. It does not have anything to do with things that do
not have to be installed because they are excluded by src.conf.

You could write an extension to the Makefile that build e.g. a
/usr/src/IgnoreFiles.inc based on the contents of /etc/src.conf. But it is
probable easier to run find(1) in /usr looking for files older than your
buildworld. 

E.g., I've rebuilt world on December 3rd. Looking for different binaries in
/usb/bin with the command 'find /usr/bin -type f -and -not -mtime 6 -ls'. If
you are sure this is all junk, replace -ls with -delete.

If you screw something up, re-run installworld. :-)
