# Running a Raspberry Pi with USB based btrfs root filesystem

This is a very advanced configuration and here as a set of notes for the more daring users building remixes.

Please note: *you will need to change ```/dev/sda``` and ```/dev/sdb``` as well as any sizes and offsets to match your needs and approach*.

|
``` bash
|
||
|
|
|

|
|
dd if=/dev/sda of=/dev/sdb bs=1M
|

|
|
parted /dev/sdb
|

|
|
mkpart
