OK.  Will package for /usr/local, and (try to) document how that could
be changed for the various distro's packaging teams.

I must have confabulated this with what I've observed on a Debian-
based distro (e.g., Ubuntu, which is what I run on my main laptop).
Sorry about that.  I think I'll have the installer check for existing
in /usr/sbin and /usr/local, somehow preserve it
(tarball in /usr/local/ntp/old_version ?) and put symlinks in
/usr/*bin to point to the stuff in /usr/local.

Let me think about this some more.  Before I publish a final RPM, I'll
solicit more feedback from you all.
