You can but it’s inconvenient: You could use a trick similar to the ‘%my-base-services’ example given at https://www.gnu.org/software/guix/manual/html_node/Name-Service-Switch.html I think we should probably change service procedures to return first-class objects rather than monadic values (by defining a gexp expander). That would make such customization easier. Additionally, we should arrange so we don’t have to define dmd services do D-Bus services, because the system bus already takes care of them. Presumably that means that we need a <dbus-service> type, which would encompass a package (e.g., GeoClue) and its associated config (e.g., a record or a file-like object.) WDYT? Thanks, Ludo’.
