With lots of help (say, all of the heavy lifting) from the Debian Raspberry Pi Maintainer Team, we have finally managed to provide support for auto-building and serving bootable minimal Debian images for the Raspberry Pi 4 family of single-board, cheap, small, hacker-friendly computers!
The Raspberry Pi 4 was released close to a year ago, and is a very major bump in the Raspberry lineup; it took us this long because we needed to wait until all of the relevant bits entered Debian (mostly the kernel bits). The images are shipping a kernel from our Unstable branch (currently, 5.7.0-2), and are less tested and more likely to break than our regular, clean-Stable images. Nevertheless, we do expect them to be useful for many hackers –and even end-users– throughout the world.
The images we are generating are very minimal, they carry basically a minimal Debian install. Once downloaded, of course, you can install whatever your heart desires (because… Face it, if your heart desires it, it must free and of high quality. It must already be in Debian!)
