Docker has been gaining a lot of hype recently for being an OS container much
like BSD Jails. Ubuntu 14.04 includes it in the repos so therefore Trisquel 7
does as well: http://mirror.fsf.org/trisquel/pool/main/d/docker.io/
I've used VirtualBox in the past and while its GPL, it pushes you to install
a non-free extensions pack. I've also noticed that Ubuntu 14.04 includes VB
in the non-free multiverse repo with the extensions pack included.
I haven't used Docker a whole lot but it does seem interesting. They also
offer an official repo with up to date packages with support for older
Ubuntus/Trisquels at http://docker.io
Anyone used this and had good experiences?
