I'm not sure if I understand how you > would do this. How would it be different from using time-machine? It is not yet supported in GWL, but it would only be a small change. The GWL has support for inferiors but currently only uses the =E2=80=9Cinvo= king=E2=80=9D Guix for packages. We could use a different set of channels per process definition. Each process runs in its own environment; it doesn=E2=80=99t have to be all done= with the same version of Guix. Whether or not to support this is merely a question of how easily workflows and processes can be reused or integrated in other workflows. --=20 Ricardo
