<para>The <citerefentry><refentrytitle>systemd-run</refentrytitle><manvolnum>1</manvolnum></citerefentry>
command allows creating <filename>.service</filename> and <filename>.scope</filename> units dynamically
and transiently from the command line.</para>
-
- <para>In addition to the various drop-in behaviors described in
- <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
- services also support a top-level drop-in with <filename>-.service.d/</filename> that allows
- altering or adding to the settings of all services on the system.
- The formatting and precedence of applying drop-in configurations follow what is defined in
- <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
- However, configurations in <filename>-.service.d/</filename> have the lowest precedence compared to settings
- in the service specific override directories. For example, for <filename>foo-bar-baz.service</filename>,
- drop-ins in <filename>foo-bar-baz.service.d/</filename> override the ones in
- <filename>foo-bar-.service.d/</filename>, which override the ones <filename>foo-.service.d/</filename>,
- which override the ones in <filename>-.service.d/</filename>.
