### Using [docker-squash](https://github.com/jwilder/docker-squash)
You can also squash the image with [docker-squash](https://github.com/jwilder/docker-squash) and then extract your layers.
sudo docker save sabayon-spinbase:latest | sudo TMPDIR=/dev/shm docker-squash -t sabayon-spinbase:squashed > /your/prefered/path/Spinbase.tar
sudo docker save sabayon/spinbase-amd64:latest | sudo TMPDIR=/dev/shm docker-squash -t sabayon/spinbase-amd64:squashed > /your/prefered/path/Spinbase.tar
You can replace /dev/shm with your prefered tmpdir
### With undocker, but squashing the layers
The squash can also been accomplished creating a container from the image, exporting it and then importing it back.

sudo docker run -t -i sabayon-spinbase:latest /bin/bash

sudo docker ps -l
sudo docker export <CONTAINER ID> | docker import - sabayon-spinbase:squashed
sudo docker export <CONTAINER ID> | docker import - sabayon/spinbase-amd64:squashed
docker save sabayon/spinbase:squashed | undocker -i -o spinbase sabayon/spinbase:squashed
Docker will loose the history revision and then you can estract the layer, using as base for chroot.
You now have the tree on the *spinbase/* directory
If you are planning to use the resulting files as a chroot, don't forget to set a nameserver on resolv.conf file
echo "nameserver 208.67.222.222" > spinbase/etc/resolv.conf
