<listitem><para>Configures the default OOM score adjustments of processes run by the service
manager. This defaults to unset (meaning the forked off processes inherit the service manager's OOM
score adjustment value), except if the service manager is run for an unprivileged user, in which case
this defaults to the service manager's OOM adjustment value plus 100 (this makes service processes
slightly more likely to be killed under memory pressure than the manager itself). This may be used to
pick a global default for the per-unit <varname>OOMScoreAdjust=</varname> setting. See
<citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry> for
details. Note that this setting has no effect on the OOM score adjustment value of the service
manager process itself, it retains the original value set during its invocation.</para></listitem>
