Hi Mark,

Sadly I've run a "guix gc" in a meantime, and I don't have uncrustify 0.68.1
locally anymore.

That said, I already had a discussion a while ago on the Guix mailing list about
GitHub-generated archives which don't have persistant hash sums.  Reason being,
apparently, because of the archive metadata.

So the best practice would be to never use GitHub generated archives and 
use git-fetch instead on the right tag.

Thoughts?
