 From the host system this image imports `podman` and `incus` so you can use both inside the container.
 
 Any application can work both ways. *distrobox* mounts wayland socket into the container so even GUI apps work seamlessly.

+There is wrong *StartupWMClass* parameter that equals `Code` in *drone-code.desktop* file. It should read:

+StartupWMClass=code
