Ext3/4 & Encryption with the sdcard

 

Hi folks - firstly, am loving using the M10. Am using it for work in place of my laptop for many scenarios - useful and fun little device. Currently I have syncing setup using Neil's open syncthing app: https://github.com/mcphail/ut_syncthing_open Works great. With a 64gb sdcard, I'm able to sync most of my documents. I'm aware how easy it would be for someone to get access to them however - pop out the sdcard and my info is yours. This is an issue for travelling - Sunday I'm off to a remote part of Indonesia for 6 weeks to run a theatre project. HIghly useful having the tablet most of the time instead of my laptop - less interested in all my data being read should the tablet (or sdcard) go missing.

So - what's involved with formatting the sdcard to ext3 or ext4, and mounting it as a drive each time the tablet boots? Is it as simple as editing /etc/fstab, or more complex than that? An ideal setup would be something like ecryptfs setup for the tablet's sdcard. Happy to experiment and report back if someone can point me in the right direction.
Cheers,

Mitchell
