export-docker's Issues

Doesn't use API; needs root; doesn't work with current version of docker

The docker binary exposes all the functions needed to do this without root access and without direct access to the docker paths. The current approach doesn't seem to be portable. Why can't the docker export command be used?

config.lxc not present in the container directory

Hi

Thanks for this project, looks really interesting

I give it a try but it's complaining that config.lxc is not present in the container directory
Is it a file docker is supposed to create on it's own ?

I'm running Docker version 1.6.2, build 7c8fca2

Any idea will be appreciated
Thanks
Damien
