I'm a bit worried about that. We already do mangle /e/n/i for dhcp-only
connections [1], and NM get's a lot of bad rep because of that.
If we do that, we should at least pop up a debconf prompt, so users can
opt-out of that process.

In the past, we had to do that, because the debian-installer creates a
/e/n/i configuration for basically every system. So NM was useless by
default, because it did not manage the device. This confused a *lot* of
people.

In d-i 7, the installer will write a NM config and *no* /e/n/i config if
NM is installed e.g. via the GNOME desktop task.

So I'm tempted to just drop the /e/n/i mangling altogether or as said,
at least put it behind a debconf prompt.

A simple warning on stdout would be trivial to implement. I fear, that
it might go unnoticed though for many. But it certainly is an option.

The wiki should definitely be updated.
