As with repositories (see patch "gitlab-backup/restore: GitLab wants
repositories to be drwxrws---") Gitlab wants proper permissions for
uploads/ - else the following check fail

    Uploads directory setup correctly? ... no
      Try fixing it:
      sudo chmod 0750 .../var/gitlab/uploads
      For more information see:
      doc/install/installation.md in section "GitLab"
      Please fix the error above and rerun the checks.

    Uploads directory setup correctly? ... no
      Try fixing it:
      sudo chown -R slapuser14 .../var/gitlab/uploads
      sudo find .../var/gitlab/uploads -type f -exec chmod 0644 {} \;
      sudo find .../var/gitlab/uploads -type d -not -path .../var/gitlab/uploads -exec chmod 0755 {} \;

and files are not served back from uploads - e.g. there is no uploaded icons shown.
