Things done
sandboxinnix.confon non-NixOS)nix path-info -Sbefore and after)Explanation: on aarch64 the interfaces is called enp3s0 instead of ens3, for some reason. Since the "predictable" naming scheme may be deterministic but not that predictable, to avoid future failure (new architectures or changes in qemu) I simply check wheter the traditional scheme (eth*) is used.
