Hmm, I did some digging and found at least UCD SNMP uses these sysctls.
Would it be juju to reuse those mib numbers/names for a different
purpose?

I could do the same as the "disknames" MIB with NUL seperated disknames,
but "diskstats" I'd want to return a NetBSD structure, not a BSD/OS
structure (and one that's future proof/64-bit safe like kern_proc2).
