Then in that case you’re just looking for a form of caching, is that
correct?

If ‘guix environment’ were 10 times faster, it’d be just fine, right?

(It’s not getting 10 times faster any time soon I’m afraid :-), but just
to make sure I understand whether we’re talking about a UI issue or a
performance issue.)
