Dear, How to track from which channel and commit the packages in a profile come from?
For example, today (time T) I run: guix package -i emacs guile -p my-env And I forgot to store the result of "guix describe". Months later, and after several "guix pull" and not changing the profile "my-env", I would like to reproduce this exact profile on another machine. It is easy to extract the version of Emacs and Guile: guix describe -p my-env So I can dig in the git history to find the commit introducing the specific version of Emacs and Guile. Well it is not convenient. :-) but doable. Then, I run: guix pull --commit=<hash> guix package -i emacs guile -p my-new-env It is also possible to extract the hashes in the store, reading the file my-env/manifest and my-new-env/manifest. And they are not the same. The Guix version that I just pulled should be anterior to the one at time T. Because maybe something in the dependencies of Emacs or Guile has changed. Well, I can list all the pulls with "guix pull" and then guess some commit. But it is not convenient, neither. What I would expect is: guix describe -p my-env Generation 5 Sep 20 2019 17:21:30 emacs 26.2 asdf12 guile 2.2.4 z56qwe (for example, I updated only Emacs once, 3 times Guile) What do you think? Do it make sense? All the best, simon All the best, simon
