Shutting Down a Robot-Mounted Pi

[dc74089]

Hi all,

We're planning on using a Raspberry Pi on the robot this year, but we're having trouble wrapping our heads around how to properly shut it down when the robot shuts off. Linux systems HATE having their power just pulled, so we've been trying to find a way to prevent corruption every time we shut off the robot.

We've been trying to get the Pi to mount its filesystem as read-only, but when we do that, networking disappears (and we need Ethernet working). Neither Stack Exchange nor the rest of the internet seems to have any remedy that has worked for us.

Teams that have used a robot-mounted Pi, how have you made sure that the Pi doesn't get corrupted when the robot power is turned off?
