RNO-G Disk Image Creation Tools

Based on RobertCNelson's omap image builder. 

This should be run on an ARM system (I use an rpi 4), probably debian for best results.  

Necessary packages: 
  git 
  debootstrap 
  m4
  dosfstools
  wget
  parted
  kpartx
	




Basic procedure: 
- set the environmental variable RNO_G_PASSWORD correctly 
- sudo ./rno-g_image.sh # (once per image). This will take a long time, and produce the image with the latest version of rno-g software.
- insert SD card
- sudo ./rno-g_deploy /dev/sdX $station_number # (once per SD card, can do different station numbers in parallel in theory). This will put the image on the SD card.

The produced-SD card will autoflash the internal mmc on first boot with a
basically identical version of itself (mounting /data from the sdcard). After
that it will boot off mmc by default unless sysboot2 is low on startup. 
This copying can date a while, you can see if it's done by checking if dd is running.
