> All other Unixes (BSD, System V, and Linux) are in some sense contaminated by outsiders who did not fully get the Unix philosophy. Both BSD Unix and System III/V added and changed things which people find objectionable and non-Unixy, so ignoring these as 'not in V7 and in the original intentions of Unix' is sometimes seen as convenient [...]
Whoa, it would be very interesting to hear some (obviously optionated) examples of this. And which modern BSD "gets" the original V7 thinking best? OpenBSD?
- chasil 5y agoI haven't ever run V7 or looked at the code, but I am going to bet that run levels in SysV init are not in V7. Perhaps some people disliked that innovation as the current detractors of systemd.

According to Wikipedia, runlevels were indeed introduced by SysV UNIX.
