When the BalenaOS is booting, it shows a splash screen. I know I can change this screen, and I’ll do that in the future. I just have a few questions about it.
I see the splash screen, but most of the time, the splash screen hides after some time and I just see the text of the OS. My Balena application starts a kiosk and is connected to a touchscreen. So users interact with the Balena system. It would be awesome if the splash screen just stays on the foreground until the kiosk starts. Is this possible one way or another?
When I want to change the splash screen remotely for all my Balena devices in the same application, how can I do this? Is there any way to change the splash screen image without having to reflash the device? If there isn’t any Balena functionality for this, but with some commands, I can setup something within my app that listens to a server for when a new splash screen is available and change it with the commands.
And last but not least, are there any more details I should know when creating a BalenaOS device that interacts with users for security reasons? There is also a keyboard connected. So I don’t know if BalenaOS gives passwordless access to the HostOS for example or other critical security components that I should know off.
Thanks in advance!
