This simplifies OS configuration: users no longer need to be aware of what a given service depends on. See the discussion at <https://lists.gnu.org/archive/html/guix-devel/2018-01/msg00114.html>. * gnu/services.scm (missing-target-error): New procedure. (service-back-edges): Use it. (instantiate-missing-services): New procedure. * gnu/system.scm (operating-system-services): Call 'instantiate-missing-services'. * tests/services.scm ("instantiate-missing-services") ("instantiate-missing-services, no default value"): New tests. * gnu/services/version-control.scm (cgit-service-type)[extensions]: Add FCGIWRAP-SERVICE-TYPE. * gnu/tests/version-control.scm (%cgit-os): Remove NGINX-SERVICE-TYPE and FCGIWRAP-SERVICE-TYPE instances. * doc/guix.texi (Log Rotation): Remove 'mcron-service-type' in example. (Miscellaneous Services): Remove 'nginx-service-type' and 'fcgiwrap-service-type' in Cgit example.
