stackoverflow link to my investigation I did ~2 years ago to check if sandboxing on Wayland with firejail is reliable: https://stackoverflow.com/questions/63802784/wayland-session-and-xwayland-configuration-at-example-of-kde

• 1. no standard way to query the config (paths)
• 2. no standard way to ensure Wayland and not XWayland is used (important for security)
• 3. no standard way to query if Wayland or XWayland are used (important for security)
