<para>When calculating candidates to relieve memory pressure, <command>systemd-oomd</command>
will only respect these extended attributes if the unit's cgroup owner, and the
owner of the monitored ancestor cgroup are the same. For example, if <command>systemd-oomd</command>
is calculating candidates for <filename>-.slice</filename>, then extended attributes set
on descendants of <filename>/user.slice/user-1000.slice/user@1000.service/</filename>
will be ignored because the descendants are owned by UID 1000, and <filename>-.slice</filename>
is owned by UID 0. But, if calculating candidates for
<filename>/user.slice/user-1000.slice/user@1000.service/</filename>, then extended attributes set
on the descendants would be respected.</para>
<para>If this property is set to <option>avoid</option>, the service manager will convey this to
<command>systemd-oomd</command>, which will only select this cgroup if there are no other viable
