I know both /proc, and /sys are virtual file-structures with pseudo files used to communicate with the kernel, but what is the difference between /proc/sys/kernel, and /sys/kernel - what is the division of power. And, is there a centralized man page for what the stuff in /sys/kernel means (like
man 5 proc)?
For instance, /sys/kernel/uevent_seqnum ? I'm sure this is a highly esoteric option that no one should change? But, what does it do? Is there a man page that might have this stuff in easily accessible layman form? If the first step isn't greping the kernel source, where would you go to find out what uevent_seqnum does?
