Hi, I find that Guix still contacts home even when passed the '--no-substitutes' flag:
$ ./pre-inst-env guix build --no-substitutes chez-sockets substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... 100.0% substitute: updating list of substitutes from 'https://hydra.gnu.org'... 100.0% @ build-started ... It would be desirable to avoid all calls home with that flag. Regards, Fede
