I have a question regarding mounting the SD on the Nano. I don't see an fstab file on the Nano and where is the "Save Fstab" file in the web interface saving the fstab file? Here is what I've done.
Nano is powered off, I put in an SD card into the Nano and powered up the Nano.
SSH as root into the Nano after power up complete.
Run df command, the SD card is not mounted. Issuing mount -a does not mount it.
I cd to /etc/ to find the fstab file is a link to /tmp/fstab. The /tmp/fstab file does not exist.
I then decided to power up the Nano first and then plug in the SD card.
