Not sure the actual authors of the various overlapping Linux network subsystems even know the comprehensive picture "inside and out" for chronic lack of consistent documentation.

Last time I managed a small «supercomputer», 50x IBM blades running Suse, it wouldn't support PXE/NFS without kernel customization, but that would void support contracts and finicky third-party software. Made a switch to FreeBSD, where everything worked out of the box one hour later. That was over 15 years ago, I have no idea how much the situation changed.

Things have improved and ubuntu is better than suse. =)

This was effectively 25k PS5's... much more powerful now.
