Revision

A revision is composed by a BSP (Pantavisor binary, Linux kernel, modules and firmware) plus a number of containers.

In order to make revisions reproducible, they can be defined ininin a state JSON. This JSON is a flat representation of a set of either binary objects or other inline JSON documents. Here you can take a look at a simple example revision formed by just a BSP and a container named awconnect:
