Include live functionality as part of the flatpak and GUI

[gbraad]

At the moment, tuhi-live is not part of the flatpak image, and it is therefore not possible to use the live mode from a platform like ublue, bazzite, etc. It would be nice if this functionality can be started from the GUI.

Note: is this not possible as tuhi-live needs root permission?

tuhi is unfortunately effectively unmaintained, until someone steps up to do some maintainership it's unlikely we'll see any new features.
