This modifies a stock debian root filesystem to be able to operate as a vision pi. It is not trying to be reproducible, but should be good enough for FRC purposes.

The default hostname and IP is pi-8971-1, 10.89.71.101. Username pi, password raspberry.

Download 2020-02-13-raspbian-buster-lite.img (or any newer buster version) from https://www.raspberrypi.org/downloads/raspberry-pi-os/ and edit modify_rootfs.sh to point to it. Run modify_rootfs.sh to build the filesystem (you might need to hit return in a spot or two).

After confirming the target device, deploy by copying the contents of the image to the SD card. dd if=2020-02-13-raspbian-buster-lite.img of=/dev/sdX bs=1M

Use lsblk to find the device and make absolutely sure this isn't your hard drive or something else.

From there, log in, sudo to root, and run /root/bin/change_hostname.sh to change the hostname to the actual target.
