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!
