While the shell scripts worked well for ... Linux Containers, or LXC, is operating system-level method for running multiple separate isolated Linux installations (containers) on a single host. Rather than simulating the computer hardware as in true virtualization, LXC uses the cgroups and namespaces functionalities of the host's Linux kernel to provide strong isolation of the container.

What I would need is to turn my container back into an image (should be doable by using lxc publish ) and either undo the changes done to it by cloud-init or at least "cock" cloud-init again so it ... I just installed a slackware64-14.2 to verify the situation and I noticed a thing (I hadn't noticed it earlier, sorry): when you use lxc-create to assemble the container the release used is current but the template is for 14.2 (maybe should be good to change this default in the template). Practical LXC and LXD begins by introducing you to Linux containers (LXC and LXD).You will then go through use cases based on LXC and LXD. Next, you will see the internal workings of LXC and LXD by considering the repositories and templates used.

LXC (Linux Containers) is a virtualization system making use of the cgroups feature of the Linux kernel.
