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
