系统在重新启动后找不到用户服务

Question

我在一台16.04电脑上做将同步设置为系统d用户服务。工作得很好。由于我升级到18.04，该服务将在重新启动时消失。

在重新启动之后，我看到：

$ systemctl --user status syncthing.service 
Unit syncthing.service could not be found.

而且syncthing确实没有运行。

下面是~/.config/systemd/user/syncthing.service (在示例之后，但请注意二进制文件位于my dir下面)：

[Unit]
Description=Syncthing - Open Source Continuous File Synchronization
Documentation=man:syncthing(1)

[Service]
ExecStart=/home/user/syncthing-prefix/syncthing -no-browser -no-restart -logflags=0
Restart=on-failure
SuccessExitStatus=3 4
RestartForceExitStatus=3 4

[Install]
WantedBy=default.target

然后我运行这个：

$ systemctl --user enable syncthing.service
$ systemctl --user start syncthing.service

按照安装说明，我最初用于安装用户服务。

在运行上述两个命令之后，我看到：

$ systemctl --user status syncthing.service

如预期的那样。然后，同步按照预期的方式工作，直到下一次重新启动。

请注意，我有一个加密的家庭dir。当我使用16.04的时候也是这样。

贷给https://unix.stackexchange.com/questions/417162/use-systemd-user-services-with-ecryptfs/545704#545704

这是氪星程序包配置中的一个bug。您可以使用快速修复: Open /etc/pan.d/公共会话并切换行

session optional        pam_systemd.so
session optional        pam_ecryptfs.so unwrap

至

session optional        pam_ecryptfs.so unwrap
session optional        pam_systemd.so

以便在pam_systemd.so之后加载pam_ecryptfs.so

您的问题与https://unix.stackexchange.com/q/417162/116970相同

我建议您在After=部分的syncthing.service上添加一个D3和一个Requires=行，以便在挂载主文件夹之后运行同步。

更具体地说，你可以尝试：

[Unit]
Description=Syncthing - Open Source Continuous File Synchronization
Documentation=man:syncthing(1)
After=home-yourusername.mount
Requires=home-yourusername.mount

...

并将您的用户名替换为您的用户名
