freebsd sysctl stuff

Even if You mount /proc on FreeBSD, it does contain only the pseudo directories with stats/information for pids. It does not contain all the Linuxisms like /proc/cpuinfo or /proc/swap or whatever.

If You take a Linux script and put it on FreeBSD it mostly ends up not working.

On FreeBSD I used a script that would gather that data without /proc, for example from sysctl.
