I agree with that, too.
It is easy, too, because the sysctl mechanism has a built-in bounds checking function.
For the seventh parameter (the parsing mechanism) you can specify something like proc_dointvec_minmax and then the last parameters can be &one and NULL. This forces the minimum value to be one.
So its trivial and built-in. While root should be able to wreck the system, he should at least have a chance in hell of knowing he is doing so. Zero may seem to be a legitimate value here...
