I have never used Flatpack but from the doc, I read:

--8<---------------cut here---------------start------------->8---
$ flatpak run org.gimp.GIMP
--8<---------------cut here---------------end--------------->8---

<https://docs.flatpak.org/en/latest/using-flatpak.html#running-applications>

Then reading:

<https://docs.flatpak.org/en/latest/desktop-integration.html>
<https://docs.flatpak.org/en/latest/conventions.html>

I am not convinced that Guix should follow the Flatpack approach by
default.  And somehow, it is not what “guix pack” already does. ;-)

About Snap, I have not been able to get the right doc.

As Mark explained,

        In order to set your environment variables appropriately for
        your entire desktop environment, you must arrange for the
        environment variable settings to be loaded before the desktop
        session is launched.  I don't remember off-hand how to do this
        in Debian.  I seem to recall that one approach is to create an
        ~/.xsessionrc file, which should be an executable Bash script
        that loads the needed environment variable settings and then
        launches the desktop environment.  Maybe there's a better way.

        I'm surprised this isn't well-trodden territory, long ago documented in
        our manual, but I guess it isn't.  It would be good if some Debian
        expert(s), or at least someone who runs Guix on top of Debian, would
        step forward to fill in the details.

it is possible to have the icons and run them from the desktop
launcher.  The configuration has to be done manually though.

Therefore, a section should be added to the manual under «Application
Setup», IMHO.


All the best,
simon
