TLDR: Dexter booting up for the first time in a new environment
This is a video of Dexter bootstrapping itself from a new SD card image. It reboots twice (after creating a partition dedicated to holding .ldimg files), then copies an .ldimg file from a USB drive to its SD card in order to achieve good performance.
What does this mean for you?
It means that Dexter is closer to being able to fully auto-configure itself so that a human being needs to do less in order to use Dexter. This is a high priority for me (to make Dexter as easy as possible to use).
