[Pkg-utopia-maintainers] Bug#530024: eth0 Wired interface not managed (on squeeze install/upgrade)

[Fabian Greffrath]

Hi,

I'd like to add to this discussion that this bug does not only affect
upgrades to squeeze but also fresh suqeeze installs. I experienced this
last week when I installed squeeze via debian-testing-i386-netinst.iso
of 2010/04/22: network-manager happily tried to connect to a wireless
network although the computer still had a cable connection to the
router.

Instead of hacking on the configuration file, couldn't this get
implemented directly in network-manager code? I mean something like

	if ((auto || allow-hotplug) && dhcp) 
		managed /* i.e. behave as if commented out
		           in /etc/network/interfaces */
