Improve initial network settings to allow static IPs

[micw]

To allow static IPs in the machines, please add the following:

• default dns should point to something like 8.8.8.8 so that name resolution works if there's no dhcp
• add a script to the image that replaces /etc/network/interfaces with a version without eth0 settings. This script can simply be run with lxc.hook.start to switch dhcp off.

Would you mind submiting a PR with that improvement? I'm not sure exactly what needs to be done =/

Thanks in advance!

I have added the pull request for debian image. For other distries it should be similar. The changes are minimal.

Unfortunately I don't have a build environment where I can test it. But I modified your original Image (cleared /etc/resolv.conf) and added my script there and testet it.

I added my example Vagrantfile which I used for testing.

Please let me know if you accept the pull request and the new images are available.

I've stepped down as a maintainer of the plugin and I'm no longer maintaining this repo. Feel free to use it as a starting point for your own boxes and if you need any help with that just LMK! 🍻
