Thank you for your inputs. >From my understanding, what you are proposing is a variant of what Pierre proposes. To be precise, at Guix Days, Pierre and I discussed to change a bit the format of <profile>/manifest in order to unify the current situation of "manifest.scm" (code evaluated) and "<profile>/manifest" (flat data); as Pierre explained elsewhere in this thread. The change of internals will not happen, IMHO, because dealing with the general case adds too much burden, and the use-case discussed here -- recreate the exact same profile from another imperative profile -- does not deserve so much attention, again IMHO. >From my point of view, it is a technical problem of internal representation and then of UI. And Ludo expressed that he is not in favor for such internal change, because a lot of reasons he explained elsewhere (argh! I do not like what I am doing here: be imprecise without citing exactly, anyway!). The best, if I understand correctly, is simply to robustify the Pierre's script and provide a clean '--export-manifest' from a profile which should be an approximation. >> Sorry I am too lazy to search, but I think I remember that at the time >> Pierre sent -- probably in the mega thread :-) -- a small script to >> extract relevant information from <profile>/manifest; the preliminary >> for '--export-manifest'. :-) > > Perhaps you are thinking of Pierre's script here? > https://lists.gnu.org/archive/html/guix-devel/2020-02/msg00154.html Yes.
