I didn't see an alternative for fine-grained labeling of sysctl - the
pathname was the only stable key I could use as an index into policy;
xattrs or the like didn't make sense there. And generating the pathname
from the sysctl tables ensured that we obtained a stable result that
wasn't mutable by userspace. Do you have an alternative suggestion?
