As a test, just check the 20 machines in my classroom after a restart, and 
found that 2 of the machines had a total of 3 services that had failed after the 
reboot. Created a script to test restarting the failed services, and it seemed to 
work fine.

systemctl restart `systemctl --state=failed | grep failed | cut -f 2 -d\  `

In both machine cases, the systemctl then reported everything was working.

The vboxdrv issue earlier would have just failed again, since the modules 
would still be missing.
