I just changed the enabled/disabled services on my /fedora26 boot partition to match the state of the services on my fedora 24 system.
Now every time I try to login, it says that /var/run/nologin exists and it won't let me.
What furshlugginer services turn this on and off? I thought it might be in gdm.service so I switched back to gdm from kdm, but it still happens.
I disabled a bunch of junk like modem manager and dropbear, nothing that I see should have the slightest connection to login (and nothing that isn't already disabled on my fedora 24 system).
