"Go trough everyting" meant all of the checking you just described. 
(Translates more or less directly like that from my native language.) My 
point is that I would have made script to deal with that. Not necessary 
automatic. And with systemd it should automatically check for any 
children left behind httpd automatically. So no need for the script and 
not really need for the other checking provided things work. Of course 
if things don't work then it's reason to complain.

So waiting isn't appreciated except for waiting done for you to log in 
(dragging yourself) to the server and doing the things described above? 
I would prefer it to be automated with message to me what happened. (In 
this instance it's not solution to everything)
