Not necessarily. Most data can be obtained through sysctl(3) - in fact, if
I remember correctly, last month someone commited changes to ps and
netstat to rely more on that instead of procfs/kmem. And sysctl interface
is _way_ cleaner than either procfs or (*shudder*) kvm.
As it is now in -current, you can retrieve exactly the same information
about processes via sysctl as via procfs (there is still a part being
obtained via kvm).
