Has anyone here taken a look at bedrock linux? It lets you have multiple linux installations coexist and interoperate (different distros mainly, but probably different copies of debian is possible)
I've been fascinated by it but never actually given it a try.
From the bedrock linux introduction page:
> Given someone already expended the effort to package the specific version of the specific piece of software a given user desires for one distro, the inability to use it with software from another distro seems wasteful.
> Bedrock Linux provides a technical means to work around cross-distro compatibility limitations and, in many instances, resolve this limitation.
