Indeed, but I only found the IRC discussion between alezost and you who explained it clearly.
I'm not sure that alezost and me was the only ones who do the same error, but maybe adding in manual a comparison between formats will be great, or maybe use another keyword for the instantiate manifest ?

No offense, but, even if didn't try too many times to understand Guile Scheme, even if i really love Guix, the last time i tried to contribute (http://git.savannah.gnu.org/cgit/guix.git/commit/?id=6e0efe8cd5c85e7b83808b466c626484274def8d) I really was not comfortable with this new language and my brain found it hard to understand the indentation rules / closing parenthesis for a first approach.
If i acquire the skills to add it before someone doing it instead of me, i will submit it with pleasure, because i'm sure to be not the only one with this need :) and will be a pleasure to support a project i want  see growing.

Nb: not directly related to this discussion, but since my last commit, i don't know if you already add it, but adding to your CI a build test for the packages with a custom store to be sure there is no hardcoded path to /gnu will prevent this kind of errors.

Thanks Ludo for always answering me, i really appreciate it.
Best regards,

Yoann
