Hi,

before creating an issue on GitHub I would like to hear your opinion on this subject. This is a follow up of this:

[1] https://github.com/grml/grml-debootstrap/issues/126

`grml-debootstrap` by default copies `/etc/network/interfaces` from the host to the target system.

Debian/stretch+ uses Predictable Network Interface Names by default whereas the current Grml release (currently 2018.12) still uses the traditional/legacy interface name (eth0).

When deploying a Debian/stretch system out of the latest Grml release (currently 2018.12) we have the situation that the `/etc/network/interfaces` file from the host is copied to the target system which then will boot with no network connection because no Predictable Network Interface Names are configured in it.

We should discuss if deploying the host `/etc/network/interfaces` file by default is (still) the best approach. I would vote for a new option like `--hostinterfaces` which does that and go for `--defaultinterfaces` as the new default option.

What do you think?
