Thanks. I'm trying to decide the best way to insert this log2ram service into the system startup order. My handicap is that I'm starting from zero knowledge of systemd :( This service needs access to the local filesystem; /var/log in particular. Ideally it also will startup before any service starts logging to /var/log, because it needs to rearrange (some may say pervert!) things so that /var/log is mapped to a ram filesystem and populated from a persistent record before any arbitrary service starts reading or writing log files in /var/log. As a special case, it maps journald's directory back to persistent store, since journald has an intelligent write strategy. So it needs to start after the /var filesystem but before any services that use it. So I'm looking for the appropriate things to put in Before and After lines for this service. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
