It takes a lot of motivation to persist. Except that "guix environment" will raise warnings.

I do not want to fight about "backward compatibility". As I said, talking about "guix environment", my opinion is that the cost of the change is low. However, we cannot know this cost, only probe and estimate: using my probings, I estimate the cost is low. IMHO, in this case, there is 2 ways to make a decision: - more probings to estimate more precisely; or - say: "no backward compatibility breakage" I am fine with both. :-) - I report my use-case: no cost at all - I propose the name "guix shell" However, I feel I have spent enough time and energy on this topic and I feel a blocking situation so I will move forward to another topic. :-) All the best, simon
