One thing that jumps out is the root filesystem, /nix/store, logs, temp files, and application data were all on the same partition. Putting /tmp, /var/log, and /nix on separate mount points (or at least using quotas) is a normal defense against exactly this kind of cascading failure. A runaway temp dir can't break your app ability to send outgoing emails. The author ended up doing this for /nix under pressure, but it's very much standard best practice in any unix/linux box, especially one with only 40GB. |
