And yet the echo shows all dots. WTH? Ahh, my bad, no damned biscuit, an extra leading slash snuck in. But if a dot and a slash are the same to sysctl, I should have a file in the wrong place? But I do not. /net is empty. It is in the right place now. And cats the correct value. Sorry about the confusion everybody.
