I also tried this in the openstack rhel-7.5 image - same issue.
There's the same issue if there is a bad entry in fstab. Systemd sulogin prompt is not shown and boot process hangs.
I've tried this with the virtual machine and fresh new 7.5 and it seems to work just fine. Are you sure that your console is set up properly? It really matters in this case.

You're right! I have just tried it in a RHEL 7.5 VM in KVM and it works fine. So it seems to be an issue with our VNC and serial remote consoles. Feel free to close this bz.
