The article at
<https://distrowatch.com/weekly.php?issue=20190624#guixsd> has a
screenshot showing ‘guix pull’ suggesting to run ‘guix pull && guix
package -u’.  This is obviously wrong.

Here is a patch to address this issue on Guix System. It creates new files in /etc/skel: an initial profile (.config/guix/initial) tgat only contains a symlink to /run/current-system/profile/bin/guix and the current profile as a symlink to the initial profile.

At first boot, and for new users, guix well be found in the current profile, and stays there after guix pull, so we don't need to use hash guix anymore.

Subject: [PATCH] gnu: system: Symlink guix inside an initial guix pull
 profile.

This patch adds an initial guix pull profile to the skeletons files used
on Guix System.  This ensures that users don't have to type 'hash guix'
after their first guix pull, and prevents 'guix pull' from suggesting to
run 'guix pull' after it finished successfuly.

* gnu/system/shadow.scm (skeleton-directory): Symlink guix inside an
initial guix pull profile.

I think this addresses the “hash guix” issue (this will no longer be
needed with this patch), but it only indirectly solves the “guix pull”
suggestion issue, right?

It prevents the suggestion, but only because the symlink appears to be
new.  If you change the mtime of the symlink, or if you run:

  GUIX_DISTRO_AGE_WARNING=1s guix pull

I think you still get the “guix pull” recommendation.

Perhaps we should add it to ‘default-skeletons’ instead of
special-casing it here?  WDYT?

Thanks for working on it!

Hi,

This old report and associated patch is uncommented since a while?

    <http://issues.guix.gnu.org/issue/36374>

What do we do?  Include the proposed patch?  Other ideas?


Cheers,
simon

I think the initial patch doesn’t work reliably, as I wrote back then,
but something like that might work.  Julien?
