<listitem><para>Unload the transient unit after it completed, even if it failed. Normally, without this option,
all mount units that mount and failed are kept in memory until the user explicitly resets their failure state with
<command>systemctl reset-failed</command> or an equivalent command. On the other hand, units that stopped
successfully are unloaded immediately. If this option is turned on the "garbage collection" of units is more
agressive, and unloads units regardless if they exited successfully or failed. This option is a shortcut for
<command>--property=CollectMode=inactive-or-failed</command>, see the explanation for
<varname>CollectMode=</varname> in
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry> for further
information.</para></listitem>
