systemd-journald keeps its logs in-memory by default.
Does anyone know what the limit is for these logs and how to increase it? From the banner at the top it seems like it is only keeping them for 3 hours:
-- Logs begin at Tue 2018-11-20 06:40:21 CET, end at Tue 2018-11-20 09:56:45 CET. --
systemd-journald to log more, but I don't want to turn on persistence because it's running on a Raspberry Pi and I want to prevent the SD card from going corrupt because of the writes.
