NetworkManager on Debian

[Hristo Hristov <xpertbg gmail com>]

Hello,

I was trying to make NM work with Debian with the help of Michael
Biebl. I found several issues:
1) When the nm-system-settings was not working (because of missing configuration 
file) the gnome applet was not showing when a wired network was enabled in the 
left-click menu, and I could not get network information from the right-click menu.
Is this expected behaviour?

2) NM 0.7 doesn't seem to use the configuration of wireless networks I had from 0.6

3) I'm trying to make NM work with resolvconf. I want to pass DNS configurations 
received from DHCP to the dispatcher and then to the dispatcher script. I have no 
knowledge of dbus, so I made an ugly patch to pass the first nameserver configuration.
Could you tell me what should be the correct way of passing the nameservers 
to the dispatcher?


Best regards,
Hristo
