Can you share how you do the SD card thing?

I'm not sure how to autorun when an SD card is inserted (using ubuntu here).

I used udev to run the script as soon as the drive is mounted. The tricky part was ensuring the drive would mount automatically when inserted, even if I wasn't logged in. I tried a range of different tools, and eventually settled on autofs.

You can use an udev rule: https://askubuntu.com/questions/489306/execute-script-on-ins...
