You can also disable journal completely using Storage=none, in which case journald would work only as a forwarder to syslog/kmsg and other configured services (if present). Again, I'd recommend going through the Storage= docs in the respective man page[0].

Storage=none has the downside, that `systemctl status` etc become less
useful. So if you have a bit of RAM to spare, I'd recommend
Storage=volatile for your particular use case.
You will have a bit of CPU overhead for journald doing the message
multiplexing but disabling it completely is not really recommended.

And personally, journalctl is just so useful. I wouldn't want to miss it.
