I have been using kiwi-ng to build an appliance, and it is great! The actual payload is small application, currently implemented using some messy shell scripts and dialog for the UI.
I want to swap to using python for the application, and a UI implemented with textual, which I have working in isolation.
Textual and its dependencies need to be installed via pip (the package versions are too old). What is the recommended way to do this? I could use something like wheel2deb to generate installable packages, and install those from local package files. I could set the appliance up with a virtual environment and install the python app, textual and the other dependencies in that. Does any body have a working example of doing this that they could point me at, or at least some general advice, before I waste lots of time on a dead end.
