[Unexpected shutdown]
Sometimes the system is not started and cannot enter the graphic interface. It is found that the service is stuck in Sendmail.
Specific cause: Baidu's sendmail service will be connected to a server in the United States when it is started. Sometimes the network is poor and the waiting time will be too long.
Solution: directly disable the startup of the sendmail service.
Systemctl Disable sendmail. Service

If you want to run the input file after the instance is started
Systemctl start sendmail. Service
* ****** You can find that it is not generally slow. ****************
If you want to use the sendmail service and do not want to lose the boot speed, I have no good solutions yet.
