Being rare will not make it practical. ;-) What I am trying to point is that considering the size of the Guix repository and its rate, the current implementation will not scale and the fallback will be impossible for the end-user. > > And it appears to me weird when we, most of the time, need a very > > restricted set of commits. > > > > We could imagine to locally create a new repo (git init) and only add > > the content of the commit specified by =E2=80=9Cguix time-machine=E2=80= =9D. > > To do that we=E2=80=99d need to say goodbye to the features I mentioned a= bove. Well, I do not see which features will be missing. I am talking about making practical: guix time-machine -C channels.scm -- shell -m manifest.scm and not having a complete working Guix. Well, I read a paper that mentions this command line, I want to inspect so I am running this command. Somehow, I do not care about the others 114456 commits of the history. And for sure "guix time-machine -C channels.scm -- describe -f channels" will not be a fixed-point. Maybe, we could imagine an option for shortcutting the complete clone and restrict to one specific commit. Cheers, simon
