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.

If anything, he gets most of his inspiration from MacOS.
He may have taken some ideas from there, but I still see more windows like ideas. We're one bad decision away from
systemd-regedit. If that happens, I might just give up completely.Considering how much systemd breaks the concept of "everything is a file", this would not surprise me in the least
"everything is a file" is such a godsend. It makes absolutely everything so much easier and intuitive. I remember trying to get an old dot matrix printer to work using a parallel-to-usb adaptor cable. Without reading any documentation or having any prior experience I tried
echo testing12345 > /dev/lp0and it just worked lol. Meanwhile my friend spent like half an hour digging in windows gui settings trying to figure out how to print to a parallel printer.I also posted about this before, but a while back I had to configure my system so that a non-root user could start and stop a root daemon without sudo. On a runit system all you have to do is change the permissions of some control files and it works. On systemd? When I looked it up, the simplest solution involved writing a polkit policy in javascript 🤮
cries It's amazing how much damage they've done to the linux ecosystem. Not just badly thought out concepts, but the amount of frustration and annoyance they caused by ramming it into existence and the cynicism it's created.
