Journal file linux

I think Linux users need to limit the journal file in size (RPi's don't have a limit set so eventually the journal will outgrow the storage),
- sudo nano /etc/systemd/journald.conf and set systemMaxUse=20M (or 2G)
- Do a journal restart: sudo systemctl restart systemd-journald

Aha... the reason I wrote this was that the parameter
SystemKeepFree was not specified on my systems and I thought journald could dump info without limit. I should have known better of course and I later found that the default value is 15% when the system starts pruning the logs.
Nevertheless, as I found that it is possible for some software to dump an awful lot of info there so if you don't analyse or use the journals otherwise, I guess some minimisation would not be unwise. If you think it useful, read
here. After all, on an RPi you are your own system manager isn't it.
