- Xorg used some kind of networking too and is getting progressively deprecated
to Wayland with a different approach.
- Traditional hackish init system is replaced to SystemD by merging,
standardizing and integrating lots of services. This is something "True UNIX
People" hate, so they forked udev and use OpenRC or switch to BSD, but there's
tendencies that BSDs might switch to the SystemD model too.
- Desktop Environments don't follow the " UNIX way " too. They use lots of
libraries and frameworks, provide configuration and even provide applications in
default metapackages too.
