+
+Only modify F<postinst>/F<postrm>/F<prerm> scripts, do not actually install any init
+script, default files, or upstart job. May be useful if the init script or
+upstart job is shipped and/or installed by upstream in a way that doesn't
+make it easy to let B<dh_installinit> find it.
+
+If no upstart job file is installed in the target directory when
+B<dh_installinit --onlyscripts> is called, this program will assume that an
+init script is being installed and not provide the compatibility symlinks
+or upstart dependencies.
+
+=item B<-R>, B<--restart-after-upgrade>
+
+Do not stop the init script until after the package upgrade has been
+completed. This is different than the default behavior, which stops the
+script in the F<prerm>, and starts it again in the F<postinst>.
+
+This can be useful for daemons that should not have a possibly long
+downtime during upgrade. But you should make sure that the daemon will not
+get confused by the package being upgraded while it's running before using
+this option.
