For example, the former wraps "faketime" around "tex -ini tex.ini" call whereas the latter wraps it around "fmtutil-sys --all" call. By the way, how do you call "faketime" from (guix build-system texlive)? It is not possible to use (gnu packages check) module from there, isn't it? Note that Guix never runs "mtxrun --generate", so I don't think UUIDs are a problem in our case. Regards, -- Nicolas Goaziou
