我有一个带有taskserver包的NixOS 17.03服务器。任务服务器服务不再启动（它曾经启动，但我无法跟踪它停止工作的精确时刻）。
以下是我的configuration.nix与taskserver相关的部分：
services.taskserver.enable = true;
services.taskserver.fqdn = config.networking.hostName;
services.taskserver.listenHost = config.networking.hostName;
services.taskserver.organisations.myorga.users = [ "henri" ];
安德错误详情：

/ nix / store / 8g6zs5xf1yvbkv8nzjgjqc3zgwjfy8a8-taskdrc确实不存在。我试图清理商店，更新和重建包，甚至升级到nixos-unstable，都无济于事。
答案 0 :(得分：1)
latest 17.03 branch has no references to taskdrc，因为that file was removed。
但是，读取该提交我们可以看到，对taskdrc文件的引用被写入${cfg.dataDir}/config文件。因此，最有可能的是，您应该从配置中删除include /nix/store/...-tasdrc行以启动服务。
为什么你经历过这样的破坏的原因是Hydra（NixOS CI）目前还没有假设，NixOS有时会升级，such migrations should be tested也是如此。
