systemd journal size

On the top line of journalctl output, I see

Oct 22 17:31:50 caddywhompus systemd-journal[203]: Allowing runtime journal files to grow to 197.8M.

I want to reduce this upper limit.  I checked the manpage of journald.conf and the setting I wanted seemed to be RuntimeMaxFIleSize.  However, according to the selfsame manpage, the default size would play out to ~72MB*.  So, I'm wondering if I've got this all wrong or something...

* The default of RuntimeMaxFileSize is 1/8 the value of [RuntimeMaxUse], which defaults to 10% of the fs.  My /var is on a 5.8GB partition, so my calculation was:

(0.1 * 5.8GB) / 8 = 72.5MB

Re: systemd journal size

"runtime" refers to storage under /run, not /var. Look for another message that mentions "system" journal files. That will be for /var.

Re: systemd journal size

Doh, had a mild dyslexic episode or something.  I had it right in my head, I swear!   But thanks for setting me straight.

In any case, the defaults for System<blah> are the same as their Runtime alternatives.  And, probably important to mention, all settings are at defaults.
