It would help with troubleshooting hardware if I could have gold images on an SD card that I could simply pop in to different embedded devices. The current .img appears to only support being burned on to eeprom in case of the BeagleBone Black. Please correct me if I am wrong!
In such a case, I would also want the SD card to be able to assume a unique identity (vs the identity of the embedded device).
Use case #1: Regression Testing.
We have a bug and we are trying to figure out if it is a result of changes in hardware or software. It would be much faster if we could change versions of the application running on the hardware by swapping SD cards than it would be trying to re-provision versions of the application through the Internet.
