I followed this excellent guide, and in no time at all was I booting the RB-100 for the first time.
- I downloaded the .ISO image from the guide.
- Inserted an USB-key of sufficient size (4GB) and waited for it to mount.
- Opened a shell and on the prompt i figured out which device my USB-key was by typing "mount" as root (see the detailed transcript of this step below).
- Unmounted the USB-key with "umount /dev/sdg1"
- Copied over the .ISO image to the USB-key with "cat mini.iso > /dev/sdg"
- Synchronized to make sure all buffers flushed with "sync"
- removed the USB-key and inserted it into the RB-100 USB port.
- Booted the RB-100 and pressed F11 key to select the USB-key as boot device.
- Inserted empty 2gb micro SD card in the slot on the RB-100
- Followed the normal Debian install procedure, answering the occasional question about identity, language, location and connection.

The USB-key is marked in green, thus the device is /dev/sdg
In the end i could finally get my uname:
