Simplified SD card storage. Based off this guide (https://openwrt.org/docs/guide-user/additional-software/extroot_configuration) from the OpenWRT documentation, extroot is a module meant to simplify SD card storage integration for fresh LAN Turtle installations. In short, the filesystem overlay used to record changes beyond the base image is moved off onboard flash storage and onto the inserted SD card. This module has been tested and verified against fresh installations running the v6.2 firmware. This module is intended for use on freshly-imaged devices. Any customizations already made are not guaranteed to persist through extroot configuration.
