Parveen suggested a tool called "sardu" (Thank you, Parveen!) and I
have downloaded and looked at it. Unfortunately, it is 32-bit only, and
it seems it only wants to install from a built-in list of images that
it wants to download itself. I haven't looked too carefully, as I was
examining it now. It is also a little difficult to work out, and not
open source. Pity, as it could be very useful. I will need to examine
it further.

Thank you very much, that was very helpful. I think I will go with this
approach, as it seems very flexible and straightforward.

I wish all of you a happy easter holiday! :)
