Is this patch acceptable? https://lists.nongnu.org/archive/html/guix-devel/2021-01/msg00070.html I reported that I compared a `guix system build` result of an `operating-system` that used the existing `(kernel-loadable-modules ...)` field, with and without this patch. The resulting builds resulted in different hashes, but with exactly the same contents in the build --- `diff -r` very quickly reported no differences because it saw that nearly all the symlinks pointed to the same gnu store items.
