You apparently misread what I wrote. I characterized as "broken" software
which *requires* a hosts file, i.e. goes directly to the hosts file to do
lookups instead of using the default resolver configuration of the machine.
I never said hosts files were "broken" _per_se_, although their practicality
is IMO quite limited (see below).

In my first decade of sysadmin experience I demonstrated, among other things,
that hosts files are not economically viable in an enterprise with more than a
few dozen networked entities. Been there, done that, switched to DNS, never
looked back. And I haven't seen anything so far in the second decade that's
likely to change that assessment...

P.S. If you're going to taunt me, at least try to be original, won't you?
Little Jimmy Keegan (of alt.flame fame) was calling me a "junior sysadmin" 6
or 7 years ago.
