+ <para>When a service unit triggered by a path unit terminates (regardless whether it exited successfully
+ or failed), monitored paths are checked immediately again, and the service accordingly restarted
+ instantly. As protection against busy looping in this trigger/start cycle, a start rate limit is enforced
+ on the service unit, see <varname>StartLimitIntervalSec=</varname> and
+ <varname>StartLimitBurst=</varname> in
+ <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>. Unlike
+ other service failures, the error condition that the start rate limit is hit is propagated from the
+ service unit to the path unit and causes the path unit to fail as well, thus ending the loop.</para>
