I checked my system and found it wasn't doing that (yes, I knew you'd be
pleased). So I downloaded
http://ftp.gnu.org/gnu/glibc/glibc-2.6.1.tar.bz2
and checked the change logs, and didn't find any reference to the change. In
fact I didn't find any reference to mdns at all in glibc-2.6.1, nor in my
host.conf(5) man page.
Are you sure it's glibc doing it? Could you point me towards what makes you
think it's glibc? Of course maybe I just missed something /really/ obvious :-)
Thanks,
