I'm looking for good documentation for sysfs; the man page is incomplete and even has one sentence that just stops half way through. I've found the Linux kernel documentation but that's a little bit too geared towards programmers as opposed to administration. If anyone can suggest a good source I'd be grateful.

The only vaguely up-to-date documentation is the kernel documentation, Documentation for /proc/sys. I’m (slowly) working my way through it, trying to ensure it’s complete, devoid of obsolete entries, and more understandable for administrators (after all, it’s part of the administrator’s guide); see the /proc/sys/kernel documentation for example. I do realise that even the “improved” documentation is still hard to understand.

Relevant settings are also supposed to be mentioned in manpages where they’re relevant, i.e. close to the point of use.
