Setup Raspbian Buster

I'm using debian 10 as my daily so these are *nix commands. Mac should work with these too but you're on your own if you're using Windows. Goal for me is to make a headless raspberry pi I can SSH into and connect to my network using Ethernet. You should be comfortable in command line if you choose to follow this guide.

Go to https://www.raspberrypi.org/downloads/raspbian and download Raspbian lite archive
unzip the image
Plug in sdcard. Run lsblk to see drives and mount points. Likely, the sdcard will show up in /dev/sda or /dev/sdb and may have some partitions like /dev/sda1 and /dev/sda2.
If partitions are mounted, unmount all of them. Ex: umount /dev/sda1 and umount /dev/sda2
Copy the raspbian image to the sdcard with sudo dd if=RASPBIAN_IMAGE_FILE.img of=/dev/sda bs=4M
Run sync to ensure the written contents are flushed
OPTIONAL: To start ssh server on boot, Unplug sdcard and reinsert to remount new partitions. You'll have two with raspbian.
