Thanks! It was exactly what I was looking for!

Do you know why it wasn't added? I used magit format-patch.

Is there a way to specify a custom location for "guix lint"? A little
bit like the "-L" option from "guix build" for example?
I suppose the right way to invoke 'guix lint' should be to use 
"./pre-inst-env" in a local
guix repository, but I didn't find where I was supposed to find it. :/

I will soon. I just tested to build the package with "rounds=2" and it
seems the package isn't deterministic. Is it acceptable or a total
no-go?

Thanks again,
