The rapidly growing log "files" aren't really systemd's fault. The same
thing would happen if you tell rsyslog to dump *everything* in a single
file and you run the same set of services with the same settings.

Ok, so systemd produces a bunch of log messages itself that you would
not see on an otherwise identical Devuan machine. But not of the order
of ~100Mb/hour, not by default at least.

The issue is with systemd's log configuration, the gory details of which
you can explore by going down the rabbit hole that starts at

https://manpages.debian.org/buster/systemd/journald.conf.5.en.html

If you don't want the systemd-journald.service to log anything, just say

Storage=none

in journald.conf and be done with it. Log messages are still forwarded
to a syslog socket so if you have rsyslog installed you should be good.

Of course, switching to Devuan may be an easier long term solution :-)
Or some other distro that let's you choose your prefered init system.

Hope this helps,
