[ubuntu-us-mi] hostname lookup bug?

[Robert Citek]

Thanks.  That is useful to know.  I checked my machine for nscd, but
alas, it is not running.  In fact, it is not even installed.

But even if nscd was running, I find it disturbing that dig appears to
ignore that I explicitly specified the name server.

Regards,
- Robert
