I'm used to using the log files in /var/log/, and I never use journalctl; what if anything would be broken if I were to disable the systemd journal persistence by setting /etc/journald.conf storage=volatile? Background: I'm trying to reduce disk activity by storing the journal in memory only.

If you crash, you lose your journal which could make some specific situations difficult to troubleshoot if the crash tied into a program which logs to journald. More or less the same risks as any volatile storage method; no power = its gone. – ReedGhost Mar 14 '22 at 23:51

but wouldn't those logs already be written to disk by rsyslog already? that is to say, is there anything important that writes only to the systemd journal? – Al Ro Mar 15 '22 at 01:45
