performance reasons, it is recommended
to write new daemons only in a way
that is suitable for
- <option>Accept=false</option>. This
- option is mostly useful to allow
- daemons designed for usage with
+ <option>Accept=false</option>. A daemon
+ listening on an AF_UNIX socket may, but does not need to, call
+ <citerefentry><refentrytitle>close</refentrytitle><manvolnum>2</manvolnum></citerefentry>
+ or
+ <citerefentry><refentrytitle>shutdown</refentrytitle><manvolnum>2</manvolnum></citerefentry>
+ on the received socket before exiting. However,
+ it must not unlink the socket from a
+ filesystem. This option is mostly useful
+ to allow daemons designed for usage with
<citerefentry><refentrytitle>inetd</refentrytitle><manvolnum>8</manvolnum></citerefentry>,
to work unmodified with systemd socket
activation.</para></listitem>
