Packaging on Nixpkgs #658

Open Rizary opened 4 years ago

Rizary commented 4 years ago

Hi! I want to properly package sozu (using systemd) in nixpkgs (in case anyone doesn't know nixpkgs, it is a package manager used by NixOS or Nix programming language). So I am looking at the https://github.com/sozu-proxy/sozu/tree/master/os-build/systemd and wondering:

  1. why it wants to write a PID file in the first place
  2. Does RUNDIR same with RuntimeDirectory?

I have asked this in gitter but no one answered. I hope this is the place to discuss on this matter.

hello! The PID file is here to help systemd, so it can follow the mater process during upgrades (replacing the current version of sozu with a new one without downtime): https://github.com/sozu-proxy/sozu/blob/master/bin/config.toml#L88-L92 RUNDIR corresponds to /run or /var/run depending on how your system is set up. We use scripts to replace those values: https://github.com/sozu-proxy/sozu/blob/005a57e8683dc563fb8165aa367d723861dfe618/os-build/exherbo/generate.sh#L7
