Thanks, but I hope to start from a bit "higher" level than this :)

Well yes, I know - I have ran a full linux distribution on these.
But I want to minimize the image size to make updates faster and
easier. I also want to remove all software that is not required
for the application to maximize reliability and security.
I called this "embedded" because the system will be a headless
server with functionality limited to one application only.

What does the CPU temperature sensor report? Mine says 43°C, but the
box is in a warm room (I guess 25°C or more). I have 4 GB RAM, an LTE
modem, and a 512 GB mSATA disk installed.

It seems to use a CF card - I want a SATA disk because I need to run
some kind of a database on the box (probably sqlite). I know there are
industrial grade CF cards, but they are pretty expensive per megabyte.
The firmware update process is what I'm mostly wondering about..
