Ok this isn't my first day at the rodeo. I think it's important to not be confused about basic functionality before proposing fixes. So before I start playing with additional users and increasing the complexity, I'd like to have a more clear understanding of the simple use case behavior. Thanks.

Gnome Network. And I should have said it's using a different naming convention than the installer. That much I know. I suspect, but don't know, if systemd or NetworkManager are getting confused somehow as a result of the different ifcfg naming, but I'd think that the name doesn't matter, but rather the MAC address in the file is being parsed.
Anaconda creates ifcfg-en5s0, but sometimes the interface doesn't get an IP address via DHCP on boot. Sometimes it does. I haven't figured out why. But if I delete this ifcfg- file, and have Gnome > Network create a new profile, it creates a new ifcfg-p5p1 file. Now the network comes up reliably on each reboot.

That makes two of us.
