Hi,

Agreed.

Unfortunately it seems that libgit2 doesn’t let us turn off certificate
verification:

  https://libgit2.org/libgit2/#HEAD/group/libgit2

‘verify_server_cert’ in src/streams/openssl.c is called
unconditionally.  So it seems that the first thing to do would be to
submit a patch upstream that would allow users to disable certificate
checks via ‘git_libgit2_opts’.

Now, by default, ‘guix pull’ honors /etc/ssl/certs.  Assuming those are
up-to-date, it should be fine, right?

Thanks,
Ludo’.
