This is the only option you should use (assuming you want volatile
logging only), leave all others commented. If you want persistant
logging use SystemMaxUse=1M instead and create the dir

Also, you need v44 for this to work correctly.

There's currently no way to turn off journald entirely, but it's on the
TODO list. When that's done you can tell journald to output to kmsg (via
systemd_journal.forward_to_kmsg=yes on the kernel cmdline) and turn both
the volatile and the persistant journal files off.
