[bug#54216] [PATCH staging] gnu: shepherd: Build it from git, and clean up shepherd-for-guix.

[zimoun]

Hi Maxime,

You are doing the discussion and we should stay focus on this patch.
:-)  Leo and me are considering better to have the substitution in a
phase, FWIW, and Attila submitted a new version.  Let's move on, again
for what my opinion is worth here.

I am totally fine to have the discussion on guix-devel or elsewhere --
I disagree on some points but I will not comment here; it appears to
me not fair to pollute by lengthy arguments the nice patch by Attila,
IMHO.


Cheers,
simon
