Mike thankyou.
I built the m2 on a usb-m2 adapter (on my laptop)
Like RaPi the FS is expanded at first boot.
All my SW built without a hitch (logger stuff, mythbackend). In this case I had to spelunk Haupauge to get the firmware.
A quick apt look. Nothing rears its head.
I'll try things now that I know.
