to activate your selected daemon. I just used the new systemd commands, thinking that would be enough. So I tried that and rebooted. Nope, same problem:
chronyd and ntpd both use UDP port 123, so each will terminate the other when it starts. If both are enabled, chronyd's unit file indicates that it should start after ntpd, so it will always "win."
You probably have both enabled, so the system boots, starts ntpd, then starts chronyd which terminates ntpd.
Disable chronyd.
Yes, indeedy.

So:

chrony has dependencies with anaconda and initial-setup. Reboot, and:

Multicast error, but no big deal. ntpq -p is reporting correctly on the broadcast servers on my network. Also, I suppose I could have just disabled chrony instead of removing it.
I had no idea about chrony and no idea it was installed *and activated* by default. So much new stuff to learn in 7.
Thank you Frank and Gordon.
