Changes that I made when upgrading from 20.09 to 21.05 isNormalUser/isSystemUser Make home folder world-readable Tor onion This post details the changes I made to my NixOS’ configuration when upgrading from 20.09 to 21.05. isNormalUser/isSystemUser § Either isNormalUser or isSystemUser must now be set. This mainly affects service user (user that is created solely to run a service). users = { fooService = { home = "/var/www"; createHome = true; + isSystemUser = true; }; Make home folder world-readable § I have a “ /var/www “ folder which I use to serve this website. Previously, chmod +xr was persistent but now NixOS always set the permission of a user’s home folder to be chmod 700 every time nixos-rebuild is executed. As a workaround, I have to configure nix to execute chmod after nixos-rebuild and during boot. system. activationScripts = { www-data. text = '' chmod +xr "/var/www" '' ; }; Tor onion § Some settings have been renamed: hiddenServices → relay.onionServices map.*.toHost → map.*.target.addr extraConfig → settings services.tor = { enable = true; enableGeoIP = false; hiddenServices = { - myOnion = { - version = 3; map = [ - { - port = "80"; toHost = "[::1]"; toPort = "8080"; } - ]; } - } - extraConfig = - '' - ClientUseIPv4 0 - ClientUseIPv6 1 - ClientPreferIPv6ORPort 1 - ''; + relay.onionServices = { + myOnion = { + version = 3; + map = [{ + port = 80; + target = { + addr = "[::1]"; + port = 8080; + }; + settings = { + ClientUseIPv4 = false; + ClientUseIPv6 = true; + ClientPreferIPv6ORPort = true; + };
