For boost Linux adoption, allow to simply develop packages for each
distribution. Zypper should accept --devel-each switch or handle virtual
--devel-each packages and redirect those requests to gnu-guix.

OpenSUSE should been integrated with gnu-guix by default and allow to start
developing packages for most distribution. But, GUIX package manager should
been adopted by more distribution firstly. GNU-GUIX is nix-based package
manager for GUIX and other distributions. OpenSUSE allows to install this
package manager from default distribution.

OpenSUSE could gather more developers by allowing to create croos-distro
packages using GNU-GUIX. When user download source package, it will install
dependencies for OpenSUSE> By installing all needed packages by GUIX, user will
be pretty sure, program will behaves similar on other distribution, if user
install it by GUIX. It is similar than flatpak approach, but it has some
advantage, like reduces space usage.
