systemctl mask 失败解决方案

报错

原因：因为已存在一个软链接

[root@rocky01 ~]# systemctl mask ctrl-alt-del.target
Failed to mask unit: File /etc/systemd/system/ctrl-alt-del.target already exists and is a symlink to /usr/lib/systemd/system/reboot.target.

解决

方案：使用-f参数，覆盖现有符号链接

[root@rocky01 ~]# systemctl mask -f ctrl-alt-del.target
Removed /etc/systemd/system/ctrl-alt-del.target.
Created symlink /etc/systemd/system/ctrl-alt-del.target → /dev/null.
