[avahi] Install Avahi on a DD-WRT router

[planet.et at gmail.com]

Hi,

I'm currently trying to install Avahi on a DD-WRT router (Asus
RT-AC66U) but I can't find the information I need.
I've also already posted my questions on the DD-WRT forums but no one
is answering. The only answer I got was useless.

Basically, I've already successfully installed Entware on DD-WRT.
I'm then ready to install the Avahi packages, but here are my concerns:

1/ Avahi packages for mipsel (RT-AC-66U) are easy to find...
http://bin.entware.net/mipselsf-k3.4/Packages.html
There are 6:
- avahi-autoipd 0.7-2
- avahi-dbus-daemon 0.7-2
- avahi-dnsconfd 0.7-2
- avahi-utils 0.7-2
- libavahi-client 0.7-2
- libavahi-dbus-support 0.7-2

I understand we need to install "avahi-utils" (which installs
libavahi-client, which also install the libavahi-dbus-support &
avahi-dbus-daemon). But do we need to install the last 2 packages
(avahi-autoipd & avahi-dnsconfd)?

2/ Once installed, are we supposed to add some specific lines for
Avahi in the startup script?
And if "yes", which ones?

3/ I've done a first test to install "avahi-utils". But it failed:

Any idea why it couldn't create directories, while few seconds before
in the same SSH session Entware could? (I installed Entware just
before).

Thanks for your help!
And sorry if my questions are a bit noob.
