Also, the preferred way now is to expose service-type objects and not provide procedures like the one above. So you can omit this procedure and instead make sure to #:export (rpcbind-service-type). So what do I then put in /etc/config.scm ? When I make your suggested change, I get this error: ./pre-inst-env guix system reconfigure /etc/config.scm guix system: error: failed to load '/etc/config.scm': /etc/config.scm:60:24: In procedure #: /etc/config.scm:60:24: In procedure module-lookup: Unbound variable: rpcbind-service If you’re willing to play a bit, it would be nice to have a system test that spawns a GuixSD with this service, and then makes sure that, say, the ‘rpcinfo’ program is able to connect to the daemon. But that’s bonus. :-) Are there some examples of existing system tests? J' -- Avoid eavesdropping. Send strong encryted email.
