I'd prefer to install - then I can go a long way to breaking things with other package installs etc, configuration, customisation, but with a view of stepping back from the cliff and recovering back to normal if it all goes wrong.

One very good think with linux is that you can generally move HD's around from machine to machine without issue.

Happy to review technically if you want a second pair of eyes. No ulterior motive other than knowing it can be useful having a second pair of eyes/perspective. Does it belong here?, possibly not, but although there is substantial documentation on LinuxCNC sites/forums, it's very regimented and fragmented, and doesn't bring different topics together well.
