One example we have is qemu virtual machine hosts where setting up the
bridge in the ifcfg scripts is easier and avoiding NetworkManager messing
things up in a non-intuitive way is critical.

Also, we have 150+ machines with fixed IP addresses, always-on connections,
and no wireless. Having NetworkManager do seemingly random things is not

FWIW we disable NetworkManager with systemctl in our potinstall kickstart
scripts and it seems to do what we want.
