Hi! Is there way to tell NM (v.0.9.8.10) not to drop ipv4ll address = eth0:avahi interface.
I don't think that is possible.
It seems that this dropping happens immediately when dhcp lease is gained. What harm it would do just preserving this interface alias?
When NetworkManager manages a device, it deletes other addresses on that interface because it doesn't know why they are there. On newer versions of NetworkManager, if you add an address (link-local or not), after NetworkManager activated the device, it would keep it. But also there is a race involved, in that the address must not be added before NetworkManager starts configuring the interface initially. Basically, NM doesn't know, what to do with this address and deletes it. Also, "eth0:avahi" sounds more like an interface-alias. That is not a separate (real) interface, just one address that is show by ifconfig tool as a separate interface (but it isn't). See `ip addr show`. Thomas
