Of course not.  But given two resumes that claim DNS experience, if one
mentions working with BIND (setting up DNS from scratch with BIND even
better), and the other has experience with djbdns, BIND will carry much
more weight.  It is the de facto standard after all.

Odds are, though, that someone who's had experience with BIND (real
experience that will come out in an interview), has had experience in
all of these areas and can answer most if not all of the questions you
pose.  So yes, BIND knowledge is a good, albeit imperfect, metric.

CNAME's are kind of funny aren't they.  Most of us probably think of the
term (colloquially), "Canonical Name," as being exactly the reverse of
what a CNAME is.  At least to me.
