Goodbye Flatpak Sunshine. Hello AppImage.
Until a deb package is available for Debian Bookworm, we can just run sunshine as an AppImage.
It is faster to startup and is a little less bloated.
The goal here is to run Sunshine as a service managed by supervisord so that it is kept running and is restarted automatically if stopped.
This just prevents people from seeing a black screen for a long time and assuming something is going wrong.
This initial setup is installaing flatpaks to the mounted home directory. This will not need to happen on every container startup. So this black screen is only a problem on the first start. But this change at least gives people something to look at.
Closes#50
Xorg was starting before udev could finish the monitor command. This prevented the X server from having access to the input devices. For some reason, any subsequent starts would be fine.
Adding a small delay to the X server start and triggering a request for device events from the kernel after a delay seems to fix this issue.
The current supervisor.d configs are configured specifically for a particular supervisor version / installation.
This decouples the configuration so we can use it on any distro.
