[bug#52174] [PATCH] gnu: Add podman

Hi Timmy,

Woow, that’s a great start, and it’ll certainly be useful to many.

Overall it LGTM.  Here are some minor issues that would be nice
addressing:

We usually have one patch per new package; IWBN if you could split this
patch accordingly.

Make sure to add ‘containers.scm’ to ‘gnu/local.mk’ too.

Please align keywords, as in:

  '(#:tests? #f
    #:configure-flags …
    #:phases …)

You can write “,commit” (read: “unquote commit”), assuming there’s a
‘commit’ local variable above.

IWBN if you could run packages through ‘guix style’:

  https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-style.html

> +    (name "conmon")
> +    (version "v2.0.30")

Please remove “v” from the version number (here and elsewhere), and…

> +       (uri (git-reference
> +             (url "https://github.com/containers/conmon")
> +             (commit version)))
                        ^
… add it here, with (string-append "v" version).

It’s ‘license:bsd-3’, per
<https://gitlab.freedesktop.org/slirp/libslirp/-/blob/master/COPYRIGHT>.

That’s it.

Could you send updated patches?

Thank you, and apologies for the delay!
