Bind is "Berkeley Internet Name Domain" software. It includes
utilities like host(1), dig(1), and nslookup(1). The format
of the output of these utilities may change slightly. If you
have scripts which parse their output, your scripts may break.
Hopefully it will be trivial to fix them. If not please let
gripe know, and I'll try to respond.
The upgrade will not propagate completely until the wee hours of
tomorrow morning (6/21/09). This will bring the linux machines
up to the same version the suns have run for a long time.
