As I said, you need to look at dhclient configuration and command line
options.  If you have NetworkManager running then it will be
controlling what dhclient does so manual editing the files will not
work. Use nmcli to see what's happening and modify the configuration.

It's not so much that editing files won't work, but that in many cases editing the files you're used to won't work. They're now generated from new flat files, and you have to dig around to figure out where the new configuration is hidden. It's a learning curve we all hate to climb, of course. Fortunately we have the source code for when the documentation is inadequate!

We see the same thing with the new firewalld. iptables didn't go away. It's just hidden behind firewalld configuration, which automatically writes iptables rules. I liken it to going from assembly language to a higher level language to describe my programming problems. And the new systems usually provide back doors that let you drop down to the more detailed implementation layer if absolutely needed.
