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.
