Or to be a member of 'systemd-journal' UNIX group. Quoting the man
page http://www.freedesktop.org/software/systemd/man/journalctl.html

"""All users are granted access to their private per-user journals.
However, by default, only root and users who are members of the
"systemd-journal" group get access to the system journal and the
journals of other users."""
