For patches that just add a new package, and a simple one, it’s OK to commit,
if you’re confident (which means you successfully built it in a chroot setup,
and have done a reasonable copyright and license auditing.) Likewise for
-package upgrades. We have a mailing list for commit notifications
+package upgrades, except upgrades that trigger a lot of rebuilds (for example,
+upgrading GnuTLS or GLib.) We have a mailing list for commit notifications
(guix-commits@gnu.org), so people can notice. Before pushing your changes,
make sure to run ‘git pull --rebase’.
