Comment 2 for bug 178244

You are absolutely right, commenting out the interface
puts it back to NetworkManager screen.

I actually agree with this change, since I never used networkmanager
And it is probably redundant with wired interfaces.
But now it is improved a lot, and thus I probably leave eth0 commented in
/etc/network/interfaces.

Although I will loose the ifup/ifdown command this way...
Maybe it is better to have an opt-in option for dual control (both ifup and networkmanager) ?

Should this bug be closed?

Thanks for the information
