Alright!

Let’s see how it behaves and if there are problems we had overlooked…

Hello!

As reported by Tobias on IRC (in the context of ‘hpcguix-web’),
checkouts managed by Guile-Git appear to grow beyond reason.  As an
example, here’s the same ‘.git’ managed with Guile-Git and with Git:

--8<---------------cut here---------------start------------->8---
$ du -hs ~/.cache/guix/checkouts/pjmkglp4t7znuugeurpurzikxq3tnlaywmisyr27shj7apsnalwq
6.7G    /home/ludo/.cache/guix/checkouts/pjmkglp4t7znuugeurpurzikxq3tnlaywmisyr27shj7apsnalwq
$ du -hs .git
517M    .git
--8<---------------cut here---------------end--------------->8---

It would seem that libgit2 doesn’t do the equivalent of ‘git gc’.

Ludo’.
