No, it just sets a flag in the texlive-texmf derivation itself (search for “substituable?” in (guix derivations)). > Based on the notes in maths.scm on > openblas, `#:substitutable? #f' also disables offloading, I don’t see this comment, but this bug was fixed last year: <http://bugs.gnu.org/18747>. :-) So I think Leo’s suggestion is a good one. I believe only texlive-texmf itself needs #:substitutable? #f. Thoughts? Ludo’.
