My thought is that this is not something I want in dh_link - dh_link has
no business second guessing the link values it gets.  Since dh_link runs
after dh_installsystemd, then we cannot even rely on dh_installsystemd
to perform a fix up either.

Which begins to smell like that either people have to update their
dh_links calls/configuration OR we roll back the dh_installsystemd
change to move to /usr.  I am not particular fan of either.  :-/

Nevertheless, I am inclined to do a rollback and then punt on the "/ ->
/usr" migration track for now.
