Automatic image creation and deployment
Setup SD-card
Since the Rapsberry Pi boards don't include any internal storage, the SD-card is a crucial component in the system. The usual work-flow is downloading the raspbian or raspbian lite image and directly flashing it on the SD-card. On the first startup, the Raspberry Pi will expand the rootfs partition to the size of the SD-card.
In this article a different approach was chosen. The SD-card will contain two independent rootfs partitions to be able to remotely update the whole system including the root file-system.
