I hadn't given much thought to how the built in would or would not be
combined with the contents of the root.hints file.
I always took it that BIND would fall back to the compiled in version if
nothing else succeeded.

The idea that a (maliciously) blank root.hints file would prevent BIND
from using the compiled in version is new to me.
