0:40:13katco(i'm sorry for this weird sentence): i'm working on some packaging for guix, and i'm trying to package a package-inferred-system system. with sbcl, guix uses the `compile-bundle-op` to produce fasl's, but this seems to not be working. that is, many fasl files are produced, but not the single `foo--system.fasl` i would expect. is there a way i can get package-inferred-systems to produce this single fasl using the `compile-bundle-op` op?
