That looks familiar. I remember similar deep blocks myself - it was nasty at |
| 28 |
the time. |

For the OP's benefit, here's a high level summary of what is going on: |
| 31 |
|
| 32 |
Avahi and mDNSResponder implement a system called ZeroConf, first designed by |
| 33 |
Apple. It's a way for machines on a network to find each other and what |
| 34 |
network features they support. These systems are quite low-level so |
| 35 |
unfortunately the implementations are often incompatible. |
| 36 |
|
| 37 |
By and large you will find that Gnome stuff supports Avahi and KDE stuff |
| 38 |
supports mDNSResponder, so the only way out of this mess is often extensive |
| 39 |
use of 'equery hasuse', 'equery depends' and 'emerge -pvt' so see what pulls |
| 40 |
in what. But first you should research what these things are so you can make |
| 41 |
intelligent decisions about what to include and what to drop. The thing that |
| 42 |
cleared it up for me was an interview with the KDE team lead responsible for |
| 43 |
these features - Google will find it for you. |
| 44 |
|
| 45 |
Personally, I find these things more trouble than they are worth. They seem to |
| 46 |
be designed for the "Apple Generation User" (whatever that is), and I have no |
| 47 |
use for that on the networks I work on. ZeroConf is not necessarily something |
| 48 |
you have to have installed... |
