Upgrading from which version?

I think you will agree though that if you have a configuration like yours for
wlan0 in /etc/network/interfaces and managed=false, then network-manager should
not manage it? The previous behaviour was simply a bug.

I also don't understand why you say that the network is taken down.
If the device is being marked unmanaged, NM should not touch it at all and as
you configured the interface in /e/n/i it should be brought up by ifupdown
during boot.

Could you please clarify what exactly happened? Was this only temporary
immediately after the upgrade? Is the problem reproducible after a upgrade?

Are you suggesting to create a keyfile connection based on the configuration
from /etc/network/interfaces?

Currently we don't do any conversion at all. We simply comment out any dhcp
iface configuration without any additional option.

If you install a new system using d-i and a /e/n/i configuration like your's is
created, the interface will be managed by ifupdown and not network-manager.

Or are you suggesting that NM still tries to take over the interface even if is
configured in /e/n/i?
