today i learned about
https://en.wikipedia.org/wiki/PostmarketOS - "an operating system primarily for smartphones, based on the Alpine Linux distribution"
https://en.wikipedia.org/wiki/PostmarketOS"Alpine Linux was chosen as the base distribution due to its low storage requirements, making it more suitable for older devices. Excluding the kernel, a base installation takes up approximately 6 MB"
i guess that would also make a more secure phone, one that is less likely to call it's mother ship.
thanks for the tip!
