Guix is mostly content-addressed, meaning that the hash identifies a file. If you don't change the hash, you're not asking for a new file, by definition. URLs are like directions (hence: ‘locator’), not identifiers. You can easily generate a bogus-but-valid hash by negating the first digit, which (in nix-base32 at least), can only be either 0 or 1. Guix will then print the correct hash of whatever it found at the URI you specified. OK to close as NOTABUG? Kind regards, T G-R
