Replacing a package system-wide
One of the things I love about Guix is how easy it is to modify dependencies, a feature I use fairly often on individual packages or manifests. However, I'm struggling to get a similar effect system-wide. Grafts do exactly what I want, but since they are defined in the upstream package definition I can't set them for my personal system. Package rewriting lets me do this on a plain list of packages, but it's really difficult to do the same for services and not possible for guix shell/other command line usage. #+begin_src scheme (operating-system ;; Package rewriting makes this fairly straight-forward (packages (fix-pkg %my-packages)) ;; But for packages deep in the dependency tree, you have to ;; track down every service that has this package as a transient ;; dependency and fix it. (services (service some-pkg-service-type (some-pkg-service-configuration (some-pkg-service (fix-pkg pkg ;; Repeat ad-nauseum )) #+end_src If you're attempting to customize, say, Xorg, this results in a very-not-fun-time. My ideal solution is something like the following: #+begin_src scheme ;; When installed in a profile, replaces pkg for everything in the ;; profile (fixed-pkg (replaces pkg) ...) #+end_src Or if that's infeasible, at least something like this: #+begin_src scheme (list (channel (name 'guix) (url "https://git.savannah.gnu.org/git/guix.git;) (replacements `((,pkg . ,fixed-pkg))) ...)) #+end_src I'm thinking this falls into one of the following: 1. I'm dumb and there's an obvious solution 2. I should be using a local checkout for this type of work and not the upstream Guix channel 3. There's no good mechanism for this, and a patch would be welcomed I'd appreciate any advice here, as this feels so much like something Guix should do surely others have stumbled on this before.

Hello, Tobias Geerinckx-Rice writes: > Nope, there is no samba service in Guix (yet :-). I've actually been working on one, which happens to be my final thesis for my school course. I completed it, and handed it in. But stopped shy from posting it to the Guix community. But I've been too quiet on this subject lately. I got a basic service running, have written some documentation for the manual. But stopped short of submitting patches. I am not convinced that it is good enough to be included into Guix though. It definetly needs better improving. Yesterday I finally started to refactor it and have prepared it to implement a config serialiser. Samba's configuration framework overwhelmed me for a bit. Anyone willing to see its basic shape? I should prepare a local Guix branch somewhere for anyone who's interested to see it. Kind regards Simon
