<listitem><para>Controls whether to
split up journal files per user. One
of <literal>login</literal>,
<literal>uid</literal> and
<literal>none</literal>. If
<literal>login</literal> each logged
in user will get his own journal
files, but systemd user IDs will log
into the system journal. If
<literal>uid</literal> any user ID
will get his own journal files
regardless whether it belongs to a
system service or refers to a real
logged in user. If
<literal>none</literal> journal files
are not split up per-user and all
messages are stored in the single
system journal. Note that splitting
up journal files per-user is only
available of journals are stored
persistently. If journals are stored
on volatile storage (see above) only a
single journal file for all user IDs
is kept. Defaults to
<literal>login</literal>.</para></listitem>
