Hi, Using Guix aabfddb (Oct 2023),
--8<---------------cut here---------------start------------->8--- $ guix build racket-minimal --no-grafts -d /gnu/store/hcdvhp36c51f6854mzggacsylkks24jj-racket-minimal-8.10.drv --8<---------------cut here---------------end--------------->8--- --8<---------------cut here---------------start------------->8--- $ guix shell racket-minimal --no-grafts --dry-run substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://bordeaux.guix.gnu.org'... 100.0% The following derivations would be built: /gnu/store/vy5y76f25ni3kxjfa8x6c3rjgvrvach1-profile.drv /gnu/store/jxbm1inf8mj7fvs8z9xxxcrlqv9i1hs7-racket-minimal-8.10.drv --8<---------------cut here---------------end--------------->8--- Well, the derivations are not the same and their output neither. --8<---------------cut here---------------start------------->8--- $ guix build /gnu/store/hcdvhp36c51f6854mzggacsylkks24jj-racket-minimal-8.10.drv /gnu/store/rvvyiy90dh2dpwn52r84xx4rsvvijz8q-racket-minimal-8.10 $ guix build /gnu/store/jxbm1inf8mj7fvs8z9xxxcrlqv9i1hs7-racket-minimal-8.10.drv /gnu/store/f2vky2mswm2h7w3jjiw7s28d25kzbmrl-racket-minimal-8.10 --8<---------------cut here---------------end--------------->8--- Hum?! Looking more closely, their builder reads, >From “guix build”: (apply invoke racket "/gnu/store/xgaj5m1yhyrc80jhx9djsvg4r7lgrz05-configure-layer.rkt" >From “guix shell”: (apply invoke racket "/gnu/store/3k9f2j9arycxd5r6fw1dpidj51pbv41n-configure-layer.rkt" And the bug is: --8<---------------cut here---------------start------------->8--- $ diff \ /gnu/store/xgaj5m1yhyrc80jhx9djsvg4r7lgrz05-configure-layer.rkt \ /gnu/store/3k9f2j9arycxd5r6fw1dpidj51pbv41n-configure-layer.rkt diff: /gnu/store/xgaj5m1yhyrc80jhx9djsvg4r7lgrz05-configure-layer.rkt: No such file or directory --8<---------------cut here---------------end--------------->8--- Well, on more more recent revisions, e.g., 06f25a9a85, I am not able to reproduce. Other said, I am not able to tell if the bug had been fixed or if it is not hit. Cheers, simon
