[Trisquel-users] Can I turn a Ubuntu into a Trisquel GNU/Linux-libre?

[andrei]

Hi,

Can I turn a Ubuntu into a Trisquel GNU/Linux-libre? I know I can turn a Arch  
into a Parabola GNU/Linux-libre.

You might be asking why would I want to do a silly thing like that :) I am  
member of the Ceata Foundation (http://ceata.org). We promote free software  
and.... we use Trisquel as a server :) The problem is that I want to use and  
share Docker.io containers and there is one that is pretty pimped up  
(Docker.io specific init process and other stuff)  
https://index.docker.io/u/phusion/baseimage/

Do you have any clue about this? Maby if I change the apt source list or  
something like that.

Thank you,
Andrei
