2022-01-19package: Honor '--dry-run' when target profile is already in store....Fixes <https://issues.guix.gnu.org/53267>. Reported by Tirifto <tirifto@posteo.cz>. Regression introduced in 65ffb9388c1c3d870cb07e4cb3ef12c9ac06a161. In the (unlikely) case where the profile we're targeting with "guix upgrade -n" or similar is already built, a new profile generation would be created and linked to despite the use of '-n'. This is because 65ffb9388c1c3d870cb07e4cb3ef12c9ac06a161 assumed that dry-run behavior would be handled solely by the build handler, which is not the case when there's nothing to build. * guix/scripts/package.scm (build-and-use-profile): Reintroduce #:dry-run? and honor it. (process-actions): Pass #:dry-run? to 'build-and-use-profile'. * tests/guix-package-net.sh: Add test. Ludovic Courtès

2021-05-28guix package: Do not warn about "missing arguments" when there's nothing to do....In some cases, running "guix upgrade" can trigger this warning, and "missing arguments" is misleading then.
