I learned how to do NetBSD kernel hacking from just the man pages. They're still my first-line documentation on the NetBSD file system work I'm doing. The state of Linux documentation is appalling by contrast.

Came in here to say the same thing. NetBSD should get more love.

Practically speaking ArchWiki has everything I'm likely to need as a poweruser, but it's not really all that comprehensive.

GNU getting a burr up its ass that info pages were the future in whenever it happened did irreparable harm to Linux.
