+ configuration items are configured in the generic <literal>[Unit]</literal> and

<para>For each path file, a matching unit file must exist,
describing the unit to activate when the path changes. By default,
limitations as inotify, and for example cannot be used to monitor
files or directories changed by other machines on remote NFS file
systems.</para>

+ <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>
