Hi Miguel, I agree that this sounds right. In practice, what do you imagine that implies in terms of system sprawl? I mean, I would imagine one is at least tripling or quadrupling the Haskell footprint.
I'm afraid this is probably edging up to a general question about art preservation maintenance. I don't mean to go off-topic. But for instance, supposing one feels obligated to stash the OS as well -- say one works in a Linux that has a rolling release schedule -- then infrastructure grows in turn. At such point, I suppose one could archive snapshots of systems with little Haskell environments per-piece. One VM could archive a number of pieces if each were of a modest size.
