{{note|The Raspberry Pi 4 is currently <em>unsupported</em> though the NixOS distribution provides upstream beta-quality images.}}
The default Linux kernel in use, is the Raspberry Pi Foundation's fork. This will change for the mainline kernel once its support for the Raspberry Pi 4 Family is good enough to allow the user to boot, configure, and rebuild a system.


The Raspberry Pi 4 Family is only supported as '''AArch64'''. Use as armv7 is community supported.

''(Until the generic image works, a [https://hydra.nixos.org/job/nixos/trunk-combined/nixos.sd_image_raspberrypi4.aarch64-linux temporary device-specific image is build on Hydra]. Note that this image is not using u-boot, but rather the Raspberry Pi specific bootloader configuration.)''
The Raspberry Pi 4B should work with either the [https://hydra.nixos.org/job/nixos/trunk-combined/nixos.sd_image.aarch64-linux generic SD image] or [https://hydra.nixos.org/job/nixos/trunk-combined/nixos.sd_image_new_kernel.aarch64-linux the new kernel variant], starting with 21.05 (or unstable).


Please note: to uncompress the .zstd, one may use the <code>unzstd</code> command (equivalent to <code>zstd -d</code>) on supported machines. The zstd commands can be accessed from the <code>zstd</code> package.
