bug#22883: Authenticating a Git checkout

[John Soo]

Hi Ludo,

I like this idea a lot since I use a checkout which I guess constitutes
a "fork" in this scenario.  I opened bug#41604
(http://issues.guix.gnu.org/issue/41604) after having trouble with a
rebase based workflow.  Some of my problems certainly come from my lack
of understanding of the authentication process and machinery.  Would the
channel introduction allow me to use the rebase workflow in my checkout?

I am not sure I am clear on how I would setup an introduction for my
local checkout.  Heck, I am still trying to figure out how to add myself
as a signer to my patches on top of master.

Thanks as always,

John
