* [bug#66296] [PATCH] pack: Allow setting a custom image tag for Docker images

From: Sören Tempel <soeren@soeren-tempel.net>

Previously, the image repository name was automatically computed from
the packages in the manifest without allowing the user to set a custom
one. As such, changing the packages in the manifest would result in a
new image name. Thereby requiring updating documentation et cetera when
using `docker load` directory on the resulting image.

Inspired by `docker build -t`, this commit adds a new Docker-specific
option to `guix pack` which allows setting a custom repository name for
the resulting image. If this option is not specified, pack falls back
to computing the name from the manifest. Therefore, this change is
entirely backwards compatible.

* guix/scripts/pack.scm (guix-pack): add --image-tag option
* guix/scripts/pack.scm (%docker-format-options): new constant
* guix/scripts/pack.scm (show-docker-format-options): new procedure
* guix/scripts/pack.scm (show-docker-format-options/detailed): new procedure
* guix/scripts/pack.scm (docker-image): allow setting a custom
  repository name for the created docker image via extra-options.

This seems to work fine, thanks. There is a line in the documentation
that states:

--8<---------------cut here---------------start------------->8---
The “repository name” as it appears in the output of the docker images
command is computed from package names passed on the command line or in
the manifest file.
--8<---------------cut here---------------end--------------->8---

Could you build upon that statement and introduce the new --image-tag
field there?

Thanks,

Mathieu

Hi,

It looks like commit 373ec2cf8ce97d5f89191c3d9211ee3a5c2067dc does not
include the pack.scm changes, only documentation.

Fixed with 435090fa3f406a76c83e11de9cd01f61ef89dcca.

Thanks for the heads-up,
