Hi Guix,
I would like to compute a derivation for a profile specified by a
manifest. I do not (yet) want to actually build that derivation.
This seems like a simple thing to do, but I haven’t been able to
accomplish this. Here is one of the things I’ve tried in “guix repl”:
--8<---------------cut here---------------start------------->8---
(begin
(use-modules (gnu packages) (guix) (guix profiles))
(derivation-file-name
(with-store s
(run-with-store s
(lower-object
(profile
(content
(specifications->manifest
(list "texlive-collection-latex"
"texlive-collection-latexextra"
"texlive-collection-latexrecommended"
"texlive-collection-fontsrecommended"
"texlive-pgf")))))))))
--8<---------------cut here---------------end--------------->8---
Unfortunately, lowering this profile object appears to invariably result
in substitutes for all these texlive packages to be downloaded, even
though I only want to get the derivation.
Am I doing something wrong here? Is this supposed to work? Is this a
regression?
