Is it possible to start NetworkManager and perhaps other services to have
network access from runlevel 1?

Runlevels are a thing of the past - since systemd came in.
One of these days someone will ask a question like this, and actually get 
"What are these 'runlevels' you speak of?" as a reply.

Let me say it again:
THERE ARE NO RUNLEVELS. The remains are just that - remains. They sort of work 
but all they do is point at system targets. You will have to learn about 
systemd and systemd targets eventually anyways...

Can I boot by altering the linux line in grub?  Adding systemd targets instead of runlevel?
