etcmanage essentially does this.  it  unpacks the new etc (and xetc) in
/usr/netbsd-etc, and then it syncs all the files into /etc in the case
when the old file is registered as automatically managed and not changed
From upstream.  Once you are set up you just run "INSTALL-NetBSD
install" from a releasedir and it all happens automatically, usually
entirely correctly.

So rather than reinvent the wheel I would suggest that you read the
etcmanage README (in the source and in the binary pacakge).  It would be
great if someone turned the README into a man page.
