[Bug 1779189] [NEW] /var/log/journal consumed all available disk space

[hackel]

Public bug reported:

Running 18.04, systemd 237-3ubuntu10, and all of my available disk space
on /var (4.3G) just got eaten up by systemd-journald.
/etc/systemd/journald.conf has all the default values (everything
commented out).  Processes were starting to crash, and I only recovered
by running "sudo journalctl --vacuum-files=1" which brought it back down
to 25M.

My understanding is that the defaults are supposed to prevent this from
happening.  I'm not familiar enough with systemd to further debug why
this might have happened.
