The path where the journal files resides or where the per-machine
subdirs reside. More specifically "-D/var/log/journal/<machine-id>" if you
only want to see the logs from that one machine. Or "-D/var/log/journal" if
you want to see the logs from all per-machine dirs in there. The files
will be interleaved as appropriate in that case. The machine ID is the
contents of /etc/machine-id.
