无法在 WSL 上的 Distrod 上的 Archlinux 上覆盖 systemd 单元的 ConditionVirtualization

Question

我正在尝试在 Archlinux 上启动 systemd-timesyncd，它是通过 Distrod 安装在 WSL 之上的。默认情况下，systemd-timesyncd 的单元文件会阻止它在虚拟化环境中启动，该单元文件有一个ConditionVirtualization=!container标志。我正在尝试使用以下配置来覆盖它：

\n

[root@valentine ~]# systemd-detect-virt\nwsl\n[root@valentine ~]# cat /etc/systemd/system/systemd-timesyncd.service.d/override.conf\n[Unit]\nConditionVirtualization=wsl\n[root@valentine ~]# systemctl daemon-reload\n[root@valentine ~]# systemctl start systemd-timesyncd.service\n[root@valentine ~]# systemctl status systemd-timesyncd.service\n\xe2\x97\x8b systemd-timesyncd.service - Network Time Synchronization\n     Loaded: loaded (/usr/lib/systemd/system/systemd-timesyncd.service; enabled; preset: enabled)\n    Drop-In: /etc/systemd/system/systemd-timesyncd.service.d\n             \xe2\x94\x94\xe2\x94\x80override.conf\n     Active: inactive (dead)\n  Condition: start condition failed at Mon 2023-02-27 10:38:46 CET; 6s ago\n             \xe2\x94\x94\xe2\x94\x80 ConditionVirtualization=!container was not met\n       Docs: man:systemd-timesyncd.service(8)\n\nFeb 27 10:38:46 valentine systemd[1]: Network Time Synchronization was skipped because of an unmet condition check (ConditionVirtualization=!container).\n

看起来 systemd 正在选择覆盖配置，但是，它似乎没有使用覆盖配置标志。

解决此问题并使 systemd-timesyncd 在虚拟化环境中运行的最佳方法是什么？

我遇到了完全相同的问题，并发现了这个对我有帮助的答案。事实证明，它ConditionVirtualization需要一个条目列表，并且必须先清除它才能更改。

我曾经sudo systemctl edit systemd-timesyncd使用以下内容创建嵌入式文件：

\n

[Unit]\nConditionVirtualization=\nConditionVirtualization=wsl\n

现在它按预期工作：

\n

~ >sudo systemctl status systemd-timesyncd\n\xe2\x97\x8f systemd-timesyncd.service - Network Time Synchronization\n     Loaded: loaded (/etc/systemd/system/systemd-timesyncd.service; enabled; vendor preset: enabled)\n    Drop-In: /etc/systemd/system/systemd-timesyncd.service.d\n             \xe2\x94\x94\xe2\x94\x80override.conf\n     Active: active (running) since Wed 2023-03-01 14:31:05 EST; 1s ago\n       Docs: man:systemd-timesyncd.service(8)\n   Main PID: 8816 (systemd-timesyn)\n     Status: "Initial synchronization to time server 137.184.81.69:123 (0.arch.pool.ntp.org)."\n      Tasks: 2 (limit: 19001)\n     Memory: 1.4M\n     CGroup: /system.slice/systemd-timesyncd.service\n             \xe2\x94\x94\xe2\x94\x808816 /lib/systemd/systemd-timesyncd\n\nMar 01 14:31:05 gnantel systemd[1]: Starting Network Time Synchronization...\nMar 01 14:31:05 gnantel systemd[1]: Started Network Time Synchronization.\nMar 01 14:31:02 gnantel systemd-timesyncd[8816]: Initial synchronization to time server 137.184.81.69:123 (0.arch.pool.ntp.org).\n

sudo systemctl daemon-reload为了安全起见，我也做了一个，但在编辑时systemctl不需要使用它。
