开机现象:
virtualBox安装增强功能后, 开机一直显示:
a start job is running for vboxadd.service
a start job is running for ...
开机速度非常慢.
1. 使用使用以下命令查看占用开机时长的服务
$ systemd-analyze blame
5min 8.837s plymouth-quit-wait.service
5min 70ms vboxadd.service
3.372s man-db.service
2.708s logrotate.service
2.539s fwupd.service
2.459s e2scrub_reap.service
1.617s dev-sda1.device
1.511s apparmor.service
1.087s ssh.service
863ms udisks2.service
2. 使用命令禁掉前2个服务
$ sudo systemctl disable plymouth-quit-wait.service
$ sudo systemctl disable vboxadd.service
Removed /etc/systemd/system/multi-user.target.wants/vboxadd.service.
