Interesting question (goes away to look at old linux distros...). Some
quite old ones have a sysctl binary - e.g. Redhat 6.2 / linux 2.2.14.
But to be on the safe side, it would make sense to do something similar
to the BSD section, and comment about older distributions maybe needing
to manipulate /proc/kernel/* directly.
