2. Making a plan

Let's start with installing a small official OS image on the SD card to make sure that we start with a working system. Until the Raspberry PI can self compile, I will use my Debian Linux PC for configuration and compilation. I'm planning to go through the following steps first:

create an image from the SD card using `dd` or `cat`, to have a reference copy of a working system
install the latest bootloader (located in EEPROM), install the EEPROM configuration tool (if it's not already installed) and adjust EEPROM configuration, adjust for speed and minimalism
self compile the Linux kernel with default configuration and install it on the SD card to have a working kernel configuration to start with
remove everything from the boot partition of the SD card which is not needed, there's maybe some trial and error involved
adjust `cmdline.txt` and `config.txt` (both located on the boot partition) for speed and minimalism
recompile kernel with speed and minimalism in mind

Once we got all of this working, I'll then look into replacing the operating system with self compiled files.
