It’s not impossible, it just takes time (how long exactly, I don’t know, we should check with the SWH folks what we can expect and what the relevant factors are.) That it takes time is acceptable IMO: we’re likely talking about disaster recovery after the Savannah repo and its GitHub mirror have disappeared. Other channels, are typically smaller but also more likely to vanish; I wonder how that affects the cooking time at SWH—again something to ask them. >> > 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 “guix time-machine”. >> >> To do that we’d need to say goodbye to the features I mentioned above. > > Well, I do not see which features will be missing. Those mentioned earlier, provenance tracking and downgrade detection in particular. Ludo’.
