Context for newbies: Linux refers to network adapters (wifi cards, ethernet cards, etc.) by so called "interfaces". For the longest time, the interface names were assigned based on the type of device and the order in which the system discovered it. So, eth0, eth1, wlan0, and wwan0 are all possible interface names. This, however, can be an issue: "the order in which the system discovered it" is not deterministic, which means hardware can switch interface names across reboots. This can be a real issue for things like servers that rely on interface names staying the same.
The solution to this issue is to assign custom names based on MAC address. The MAC address is hardcoded into the network adaptor, and will not change. (There are other ways to do this as well, such as setting udev rules).
Redhat, however, found this solution too simple and instead devised their own scheme for assigning network interface names. It fails at solving the problem it was created to solve while making it much harder to type and remember interface names.
To disable predictable interface naming and switch back to the old scheme, add net.ifnames=0 and biosdevname=0 to your boot paramets.
The template for this meme is called "stop doing math".
That's just dconf lol. It sounds great in theory -- after all, isn't bringing standardization to a chaotic battlefield of different formats a good thing? But in practice it's absolute garbage. I would much rather just edit a config file. Heck, even if you program uses some obscure config format like xml or something language-specific like
.luaor.py, I would much rather take a few minutes to learn the specifics of your format than fuck around with dconf. Fuck dconf.Yes, yes, but now lets take that, make it dependent on the session management system and dns resolver for some reason, make the command longer and more convoluted and store the results in one or more of a dozen locations! It'll be great!

Dconf is bad, just imagine how bad a systemd version would be.
