Hi!

Thanks for the feedback.

Could you elaborate on 'tons of things' ? :-)  And why does it break
rebasing?  I rebase my branches often while signing the commits, so I'll
need more details to understand the issue.

The idea was to distribute the basic configuration that makes
collaborating on Guix easier, by auto-configuring things that previously
were left to do manually.  By having non-committers also follow the
committers' flow, it also prepares them to become committers, if they
wish :-).

This one is a clear problem, for example causing issues to build a
release tarball of Guix where git shouldn't be a requirement.  It should
be easy to fix with a test as you suggest.
