Thus if you symlinked /var/log/munin to /tmp/munin-log (or something similar), then /tmp/munin-log would not exist for the new munin-node process. Are you using such a setup? In this case I would recommend to mount a tmpfs onto /var/log/munin or /var/log instead. The munin service files supports such a read-only customization without changes. Cheers, Lars
