我今天注意到，我几天前禁用的systemd定时器仍在运行。 再次禁用它似乎没有效果。 我可能在这里错过了一些基本的东西（我对systemd很陌生），但是我所做的只是遵循网上一般的build议。
root@nla-cloud:/var/log# systemctl list-timers NEXT LEFT LAST PASSED UNIT ACTIVATES Fri 2017-10-13 00:00:00 UTC 13h left Thu 2017-10-12 00:00:01 UTC 10h ago delete_dummies.timer delete_dummies.service 没有反馈在这里说符号链接删除（这是什么发生了我第一次禁用它 – 日志丢失）：
root@nla-cloud:/var/log# systemctl disable delete_dummies.timer
是的，仍然活跃，等待…
root@nla-cloud:/var/log# systemctl status delete_dummies.timer delete_dummies.timer - Deletes dummy devices at midnight Loaded: loaded (/lib/systemd/system/delete_dummies.timer; disabled; vendor preset: enabled) Active: active (waiting) since Thu 2017-10-05 09:22:44 UTC; 1 weeks 0 days ago Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable.
计时器：
[Unit] Description=Deletes dummy devices at midnight [Timer] OnCalendar=daily Persistent=true [Install] WantedBy=multi-user.target
单元：
[Unit] Description=Delete dummy device entries. [Service] Type=simple ExecStart=/usr/bin/delete_dummies.sh
我喜欢systemd。
