Description Igor Stoppa 2015-05-05 08:24:57 UTC

When creating an image, there is the possibility that the image will be deployed on a SD card, rather than on a USB stick or HDD.

UUIDs are the only way to produce an image that will be not affected by the target media.

The alternative is to manage separately the creation of different images, one which will use /dev/sd... and one which will use /dev/mmcblk... 

This is sub-optimal and prevents various cases, for example the verification of exactly the same binary on different media.
