Cool, i have no problem replacing my resolvers with bind9, as there are no
specific config issues i have to worry about...at the moment all my
resolvers are running named, which as you suggest below is not an
issue...so assuming sun bring out a patch, we should be okay to patch all
of internal and external servers which use the customer resolvers. my other
servers are primary and secondary servers running named, i assume that
there is no inherent risk in leaving these at bind8.2.3 in the short-term,
as as you say, any calls to named from externally will use the internal
resolver functions in named...
