    The 2.5 development only tree had a ton of behind the scenes big long projects that weren’t visible to users until the stable 2.6 dropped and everything suddenly changed.

    Like a complete redesign of the scheduling code especially but not exclusively for multiprocessor systems, swapping much of the networking stack, and the change from devfs to udev.

    If you hold udev up next to devd and devpubd that solve similar problems on the BSDs, it’s a clear leap into “Linux will do bespoke binary interfaces, and DSLs for configuration and policy, and similar traditionally un-UNIX-y things that trade accepting complex state and additional abstractions to make things faster and less brittle to misconfiguration” which is the path that the typical Linux pluming has continued down with eg. Systemd.

    A lot of modern Kernel development flow is about never having that kind of divergence and sudden epoch change again.
