Fortunately; there is another option: Use the Flash Tool Lite Flash Tool Lite User Manual | Intel® Developer Zone
This process should allow you to have 1.4G as root. Try it out and let us know the outcome.
first tx hwNewbie and Cmatal_intel for answers.
thx for the answer, but i try to do what you suggested and this work fine and when i do reboot to edison the kernal is stuck and i send the edison to junk... not rly, but the edison stuck in reboot and i need to run command in boot "run do_ota" and this fix that but the memry go full again, so thx for the answer but think again before you suggests danger answer.
but anyway thx on your try.
i did that and this work perfect, very thx.
Cocool, sorry it didn't work for you but this wasn't theoretical. This is how I setup my own Edison, and it works fine, persists over reboots etc.
How I do this though is to move /usr to /home/usr as the first thing after a fresh setup. Maybe trying to move it after installing several packages and so on impacts it (I am not sure, just speculating).
Bottom line, I am glad you found a solution that works for you.
