reboot报错Failed to start reboot.target的解决办法
reboot
Failed to start reboot.target: Activation of org.freedesktop.systemd1 timed out See system logs and 'systemctl status reboot.target' for details.
尝试强制重启：
reboot -f
或者
systemctl --force --force reboot
参数解释：
man reboot
-f, --force
Force immediate halt, power-off, reboot. Do not contact the init system.
man systemctl
reboot [arg]
Shut down and reboot the system. This is mostly equivalent to start reboot.target --irreversible, but also prints a wall message to all users. If combined
with --force, shutdown of all running services is skipped, however all processes are killed and all file systems are unmounted or mounted read-only,
immediately followed by the reboot. If --force is specified twice, the operation is immediately executed without terminating any processes or unmounting
any file systems. This may result in data loss.
If the optional argument arg is given, it will be passed as the optional argument to the reboot(2) system call. The value is architecture and firmware
specific. As an example, "recovery" might be used to trigger system recovery, and "fota" might be used to trigger a “firmware over the air” update.
