I have several Raspberry PI units, but I always use the customized flavor of Linux (Raspbian) for installs.
Does the Raspberry PI support the installation of an unmodified ISO from the various Linux distributions? (Ubuntu, Debian, Fedora, etc.) Can I download an ISO from their website
dd it to a USB and then get an installer to work?
Along those lines, are there any other hardware devices (Hummingboard, Arduino, BeagleBoard, etc.) that support unmodified installs? (If this isn't the place to ask that question, what other Stack Exchange site would be more appropriate?)
