Maybe not that big (It's 5" instead of 10") but I just bough an M5Paper for a similar use at home, probably in "collaboration" with my Home Assistant. Still haven't tested it but I've heard good things about it.
You can start developing easily using their easy development tool called UIFlow, that's block based like Scratch ( https://flow.m5stack.com/ ), or go "advanced" and use MicroPython or Arduino, as it's core is an ESP32
I actually just got one of those devkits, it was only slightly more expensive to get this than just the eink display. and there is ready to go weather display software already available.
Care to tell more about what you did with yours and where to start if you‘d want to install a Linux environment? Sounds like a great idea since these precious e-ink screens shouldn’t end up on a landfill yet!
I wish something hackable like this was commercially available (without surveillance/data harvesting.)
