Pinning to a commit

[Etienne Carichon via <help-guix@gnu.org>]

Hi to the community,

For the last days, I study how guix works through the wonderfull guix manual, but there are still a few questions that come to my mind.
One of those questions is how channel pinning is supposed to work.

I want to run guix the from the latest commit, for development purpose, currently :
'e2ba58a67f8ebf1e9c0b1bc082db79ffae42a46f'

After a 'guix pull', when I call 'guix describe', it returns the following output :

<-------------------------------------------------------------->
Generation 2 May 01 2024 14:01:44 (current)
guix 7866294
repository URL: https://git.savannah.gnu.org/git/guix.git
branch: master
commit: 7866294e32f1e758d06fce4e1b1035eca3a7d772
<-------------------------------------------------------------->

And this, even if my '${HOME}/.config/guix/channels.scm' is pinning the channel
the 'e2ba58a67f8ebf1e9c0b1bc082db79ffae42a46f' :

<-------------------------------------------------------------->
(list (channel
(name 'guix)
(url "https://git.savannah.gnu.org/git/guix.git")
(branch "master")
(commit
"e2ba58a67f8ebf1e9c0b1bc082db79ffae42a46f")))
(introduction
(make-channel-introduction
"9edb3f66fd807b096b48283debdcddccfea34bad"
(openpgp-fingerprint
"BBB0 2DDF 2CEA F6A8 0D1D E643 A2A0 6DF2 A33A 54FA")))))
<-------------------------------------------------------------->

Am I missing something ?
