Another bit of info.
Prod node 2, upgraded from 4.4 to 5.0, keeps the old eth0/eth1 interface naming, and it has the /etc/udev/rules.d/70-persistent-net.rules file
Prod node 1, reinstalled from scratch 5.0 release, has the "new" renaming of interfaces to enp4s0 or whatever, and I manually created the /etc/udev/rules.d/70-persistent-net.rules file to match the relevant MAC address and other info
However, Prod node 1 does not honour the udev file. My reading suggests I need to add GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0" to grub, however Prod node 2 does NOT have this in their grub conf file, so I am very confused as to how Prod node 2 is doing what I want, without having the configuration I would expect.
I have been trapsing across the config files for quite a while now, and I'm going to hold off on adding the grub flag, but I'd like to have some dev direction as to how this was handled, as I would want both nodes to be consistently configured.
