Not content with systemd clambering all over my Ubuntu box, I went on a rather lengthy voyage of discovery trying to find out why each and every single ftp transaction was cluttering up my syslog, despite having the usual two logs in my /var/log/proftpd path.
Every time my webcam uploaded a single JPEG photo/snapshot, systemd made entries in my syslog, a minimum of 3 lines at a time. If you know me at all, there's nothing I hate more than 'not being able to see the wood for the trees'. All these entries made looking through my syslog a real chore. systemd is the biggest piece of crap. I'm going to be looking at Devuan in the very near future. Anyway, rant over. Here's how to disable the barking-mad systemd entries for ftp transactions in the syslog:
R2D2:/ $ sudo /usr/bin/systemd-analyze set-log-level notice
You will need to add this line to the file /etc/rc.local so that it runs on boot.
