[Message part 3 (text/plain, inline)]

Steps to reproduce:
1. Install any flatpak app from a GNOME environment
2. Try to launch the app from activities  (the gnome menu accessible 
through super-key) and expect it to not find it

To fix this i was told that the path 
`~/.local/share/flatpak/exports/share/applications` has to be appended 
in the environmental variable XDG_DATA_DIRS

I think it may be that Sway will only honor ~/.profile and not
~/.bash_profile, or something like this?

I think the right approach here could be a home service as Liliana
suggested, to automated the required configuration.  I wouldn't like to
have to maintain this in Guix itself since flatpak is not a standard
component of it, and it seems being opt-in would be less surprising.

The same way GNOME on other systems doesn't recognize Guix installed
applications without you configuring your session files accordingly.

I'll now close this.  A guix home "service" patch would be welcome
though.
