I've been working on this for quite a while now and have spent close to 3 days looking for an answer for this...
Every time I boot my Omega2+ its a blank slate. I've updated to the latest firmware
or at least it's what I believe is the latest firmware.
Something as simple as
and then rebooting clears 'newfile' from the device.
I have a feeling that there is a simple answer to file persistence on reboot but I haven't found it.
As another note all of my installed packages from 'opkg install <package_name>' also get removed on reboot as well as the console that gets installed from the setup wizard (this https://docs.onion.io/omega2-docs/using-the-omega-installing-the-console.html)
