Several kernel options are marked to install as default, yet the help instructs "If unsure, say N." or the equivalent. This isn't a big deal and I'm certainly not losing sleep over it, but it seems contradictory. Does it make sense? If so, what's the logic? Two examples from linux-3.8.1 General setup: General setup/Control Group support ---> - Say N is unsure. General setup/Kprobes - If in doubt, say "N".
