Our software can also be deployed in a VM; I have tried that but found the overhead of using a VM (build times, test job run times and the fact that you have to have a working virtualisation setup) rather large. Instead now I (and many of my colleagues) use a few scripts to maintain the chroot system for our software. This also seems easier to implement across multiple linux distros without much fiddling (it's after all a few scripts that uses chroot to setup the environment). To give you an idea about the "easy on various" distros bit, we have tried this on Arch, Ubuntu, Fedora and Debian. Getting it to work on Fedora required some extra effort to get the SELinux labels for the chroot'ed directory hierarchy correct. Hope that answers your question. -- Suvayu Open source is the future.
