+ <listitem><para>Control whether the
+ container's journal shall be made
+ visible to the host system. If enabled
+ allows viewing the container's journal
+ files from the host (but not vice
+ versa). Takes one of
+ <literal>no</literal>,
+ <literal>host</literal>,
+ <literal>guest</literal>,
+ <literal>auto</literal>. If
+ <literal>no</literal> the journal is
+ not linked. If <literal>host</literal>
+ the journal files are stored on the
+ host file system (beneath the host's
+ <filename>/var/log/journal</filename>)
+ and a per-machine subdirectory of this
+ directory is created and bind mounted
+ into the container at the same
+ location. If <literal>guest</literal>
+ the journal files are stored on the
+ guest file system (beneath the guest's
+ <filename>/var/log/journal</filename>)
+ and a per-machine subdirectory of this
+ directory is symlinked into the host
+ at the same location. If
+ <literal>auto</literal> (the default)
+ and the subdirectory of
+ <filename>/var/log/journal</filename>
+ exists as directory it is bind mounted
+ into the container, but nothing is
+ done otherwise. Effectively, booting a
+ container once with
+ <literal>guest</literal> or
+ <literal>host</literal> will link the
+ journal persistantly if further one
