Hey, Just ran into this issue myself. Was able to work around it by editing the file: `/var/run/docker/containers//hostconfig.json` to point to the same `runc` executable that is listed by `guix package -I runc`. After editing, simply run `sudo herd restart dockerd` and the edited container will work as it used to. Dunno how we might implement this kind of edit into the procedure that updates `runc` in the first place, but it seems like that could be a solution. Ideally, it would just use `runc` in the `$PATH`, but then `runc` becomes a propagated input. Hope this helps. -- Christopher Rodriguez
