Now ‘id’ and ‘groups’ work fine in containers. Does it solve the specific problem you were having? Maybe there are other things that would need to be done, dunno. I’m thinking we should change ‘guix environment -C’ to map to a UID other than zero, at least by default. When developing code, some tools may behave differently when running under UID 0 and that’s rarely what we need I think. Thoughts? Ludo’.
