What I would love to do is to setup a "base" container which contains the OS
and the required
packages (the common part) and to create several - customizable - instances of
this container.
Roberto,
My LXC creation script "lxc-ubuntu-x" has this feature. You can
create any number of "templates", where each template features both a
unique tarball (with all packages, etc. already installed) and also a
customized set of configuration commands (so you can run your own setup
programs and/or shell commands).
It caches everything in a tarball so that deployment of a brand new
container takes about ~4 seconds. (This is because untarring a tarball
is much faster than copying individual files, or running debootstrap).
It has also allows you to create complete deployments without human
interaction, and it takes care of generating unique MAC addresses, SSH
server certs, SSL certs (for LAMP), and a default new user with a
pre-installed .ssh/authorized_keys file.
The code is on github. Homepage is at:

Thanks,

All the data continuously generated in your IT infrastructure
