The h1guardian1 journald config was changed to hold onto logs for only the last 2 months, and to increase individual log file size from 128M to 512M. This should significantly speed up guardian log access. The change mirros what was done at LLO in November (LLO alog 50166).
etckeeper was also installed on h1guardian1 to track config changes in /etc, and the above change was committed:
