The LFH, as much as they would like it to be, isn't an
end-all be-all guide.

It's a standard on RHEL, CentOS, Scientific, OEL, Fedora and all
their respins. The above description is accurate. /sys was
meant as a read-only replacement for /proc which is, technically
unless they've changed it yet again, deprecated.
/sys exports much more to userland than do the older /proc
interfaces.

"/sys acts as a window into the internal workings of the kernel
and is used by some programs; most mere mortals need not tread

Yes, indeed. Sorry to have overlooked that; good catch.
