Hi, I'm not 100% sure that what you are doing is correct in the Guix-sense. Anyway, what's important is that you never delete from the /gnu/store manually, always use guix gc, as you did. To prevent things in the store from garbage collection, you can use the additional build parameter "--root=3Dfile", see here: https://www.gnu.org/software/guix/manual/en/guix.html#Additional-Build-Opti= ons i.e. guix build ... --root=3D/home/me/my-gc-root That would prevent the gc to remove that file, as long as that created link points to the store entry.
