This is a reminder to myself on how to make the systemd journald relay everything through rsyslogd, so we get useful info in /var/log.

In /etc/systemd/system/syslog.service, set

Requires=syslog.socket

In /etc/rsyslog.conf, set

module(load="imuxsock" SysSock.Name="/run/systemd/journal/syslog" ) # provides support for local system logging

then restart rsyslogd.
