+USERS AND GROUPS:
+        Default udev rules use the following standard system group
+        names, which need to be resolvable by getgrnam() at any time,
+        even in the very early boot stages, where no other databases
+        and network are available:
+
+        tty, dialout, kmem, video, audio, lp, floppy, cdrom, tape, disk
+
+        During runtime the journal daemon requires the
+        "systemd-journal" system group to exist. New journal files will
+        be readable by this group (but not writable) which may be used
+        to grant specific users read access.
+
+        It is also recommended to grant read access to all journal
+        files to the system groups "wheel" and "adm" with a command
+        like the following in the post installation script of the
+        package:
+
+        # setfacl -nm g:wheel:rx,d:g:wheel:rx,g:adm:rx,d:g:adm:rx /var/log/journal/
+
+        The journal gateway daemon requires the
+        "systemd-journal-gateway" system user and group to
+        exist. During execution this network facing service will drop
+        privileges and assume this uid/gid for security reasons.

 WARNINGS:
         systemd will warn you during boot if /etc/mtab is not a
         symlink to /proc/mounts. Please ensure that /etc/mtab is a
