Hi!

Starting a dive through this amazing patch series…

You can remove the ‘bootstrap-origin’ call: it’s only useful when there
are patches or snippets.

You can add a mirror://gnu/guix/mirror URL and we’ll copy it to
ftp.gnu.org.

You can make it a gexp like so:

  (arguments
    (list #:guile …
          #:builder
          #~(begin
              (use-modules …)

              (let ((source #$(package-source this-package))
                    (tar #$(this-package-input "boottar"))
                    (out #$output))
                …))))

> +           (setenv "PATH" (string-append tar "/bin:"))

> +           (mkdir-p out)
> +           (copy-recursively "bootstrap-seeds" out)
> +           #t))))

You can remove the trailing #t.
