Well, rebuilding guix with a freshly built guile-git (against the newer
libgit2) seemed to resolve the issue on at least one build, so will
update in Debian and see if that helps in general...

Well, sure. I just have not personally maintained many packages that
need to worry about those kinds of headaches too much... Debian still
requires manual intervention to handle it in some form and lacks the
elegance of guix in this regard. :)

Oh wow, it is already in debian experimental. :)

Will have to try building guix with it, now... and mentally prepare for
the possibility of more test-suite failure wrangling.


live well,
