I think sysctl is not the same as sysfs in Linux. The sysfs is a vfs that is mounted on `/sys`, whereas sysctl only controls the settings that are available inside `/proc/sys`.
Not all the settings in `/sys` is related to the kernel. So it's probably better for it to be located in `boot.sys`. For example /sys allows you to change CPU frequency. See: * http://www.noah.org/wiki/sysctl_and_sysfs * http://people.ee.ethz.ch/~arkeller/linux/multi/kernel_user_space_howto-2.html On BSD I think it's different, in that sysctl there might be able to do everything.
