Comment 5 for bug 975125

Ok, thanks. This isn't an ifupdown bug either then; it's working as designed, which is that if there's a network interface marked 'auto' in /etc/network/interfaces, the boot waits to give it a chance to come up before proceeding to start services.

This is not an issue when installing from the desktop CD, or when installing a server system using the same network interface that will be used post-install; it's specific to the method you used for installing (booting mini CD, installing over ethernet, then switching to wifi).

So to fix this issue, you should delete the eth0 lines from /etc/network/interfaces.

I'm reassigning this bug to debian-installer. Maybe it should be configurable whether the config for the interface used for installation gets copied to the installed system.
