===Setup environment===

===Flash vs micro SD===
* micro SD cards work best for development
** replaceable
** changes get written to the card, no extra sync required

* flash works best for a production system:
** non-replaceable
** limited write cycles
** because of overlayfs changes need an extra sync (overlay_sync) and a proper reboot to get written to the flash.
