I had to make several adjustments to make it work with nixos: * Replace relative config file lookups with ENV variable. * Modify gitlab-shell to not clear then environment when running pre-receive. * Modify gitlab-shell to write some environment variables into the .authorized_keys file to make sure gitlab-shell reads the correct config file. * Log unicorn output to syslog. I tried various ways of adding a syslog package but the bundler would not pick them up. Please fix in a better way if possible. * Gitlab-runner program wrapper. This is useful to run e.g. backups etc. with the correct environment set up.
to regenerate Gemfile.nix and Gemfile.lock you need to % nix-build bootstrap.nix % cp result/Gemfile.nix ./ % cp result/Gemfile.lock ./
