Subject: Manual section on building Guix from Git is incomplete

Hello!

The manual describes how to fetch Guix from Git in section ‘14.1
Building from Git’, including how to verify the authenticity of the
copy. Quoting the part in question:

> If you want to hack Guix itself, it is recommended to use the latest
> version from the Git repository:
>
>      git clone https://git.savannah.gnu.org/git/guix.git
>
>     How do you ensure that you obtained a genuine copy of the
> repository? To do that, run ‘guix git authenticate’, passing if the
> commit and OpenPGP fingerprint of the “channel introduction” (*note
> Invoking guix git authenticate::):
>
>      guix git authenticate 9edb3f66fd807b096b48283debdcddccfea34bad \
>        "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA"
>
> This command completes with exit code zero on success; it prints an
> error message and exits with a non-zero code otherwise.

I have encountered two problems here:

  1.‘guix git authenticate’ only works after the branch ‘keyring’ has
     been set up locally; I’ve been told to achieve this with the
     command ‘git fetch upstream keyring:keyring’, but ‘git checkout
     keyring’ has worked for me, too. After that, it seems to be
     necessary to switch back to the master branch to successfully run
    ‘guix git authenticate’. I think the commands for this should be
     included in this section.

  2. The word ‘if’ seems to be a typo of ‘it’. I first thought that the
     sentence was incomplete and that the command should pass if the
     commit and the fingerprint [did something]. :)

Not sure how the first one would be solved the best.

Best of wishes
