I'm preparing a series of articles on FreeBSD's sysctl interface -- not the inner workings, merely "What is sysctl, what is it good for, and how can it solve my problems?" The magazine editor specifically asked for it, so I'm pretty sure it'll see print. ;) I've always had the impression that the sysctls available on a system are dependent on the kernel configuration, but have never been able to verify this. I've gone through a variety of kernel source, but there's so much of it I can't be sure I have a definitive answer. I've also sat down a couple times and built a variety of kernels, trying to verify this with different combinations of options. Either I've been picking the wrong options, or the sysctls on a system are fixed. Can anyone confirm/deny this? What are some kernel options that carry along their own sysctl trees, if this is the case?
