I've been trying to see it do something usefull, but it hasn't been anything but an excedrin headache here. If it ever had a legit use, I've not observed it do anything but break networking by feeding bogus info into the system. That its very good at.

You do the install there by dd'ing the complete filesystem image to the boot media, usually a u-sd, so you get that crap regardless and must physically remove it before a staticly defined, hosts file based network that has not had a functioning dhcpd server even in my original 1998 install of red hat 5.0 will work. > > [1] https://qa.debian.org/popcon.php?package=avahi > > Reco Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
