: According to OpenBSD CVS logs, zyd(4) was based on atu(4) and atu(4) 
: was based on wi(4) in turn.  Originally wi(4) was written by Bill

Well, maybe not.  With so many transitive things the only commonality
between wi.4 and zyd.4 is the license.  I doubt that's enough to
retain the copyright notice.
