Re: Staring mysqld with systemd hangs at "Activating" -- and there's not much on Google

[Authorized User]

I turned on systemd debug logging the information seems helpful, but I'm not sure what to make of it. Based on my non-expert eye, it would seem that the mysqld process is indeed forking, but it is not telling systemd that it can go on with its business. (Btw, selinux is in permissive mode.)
