:I'd like to add something like the attached patch to the vkernel to
:let the user know that vm.vkernel_enable = 0. I spent quite a while
:today chasing down why mmap() was failing before remembering that I
:needed to turn vm.vkernel_enable on.
That's fine, but adjust the sysctl to only read the variable, not
set it also (pass NULL for the newp argument to sysctlbyname).
