Hi!

For the record, that’s a 6% increase:

--8<---------------cut here---------------start------------->8---
$ guix size guix | tail -1
total: 633.0 MiB
$ guix size guix git-minimal | tail -1
total: 675.7 MiB
--8<---------------cut here---------------end--------------->8---

(Of course it all adds up; I’m not saying we can dismiss it.)

In the context of <https://issues.guix.gnu.org/65866> plus the lack of
GC in libgit2 discussed in <https://issues.guix.gnu.org/65720>, my
inclination is to include that hard dependency on Git.

That’s not a happy choice for me, but it has the advantage of solving
two immediate problems.

I would revisit it as soon as libgit2 supports shallow clones (which is
coming, as you write) and GC (or a workaround to that effect).  SHA256
may also soon be a requirement: we’ll need to be able to clone repos
that use it.

How does that sound?

Ludo’.
