NixOS on ARM: Difference between revisions

Line 529:

The installation image is actually a MBR partition table plus two partitions; a FAT16 /boot and a ext4 root filesystem. The image is designed such that it's possible to directly reuse the SD image's partition layout and "install" NixOS on the very same SD card by simply replacing the default configuration.nix and running nixos-rebuild. Using this installation method is strongly recommended, though if you know exactly what you're doing and how U-Boot on your board works, you can use nixos-install as usual. To help with the SD card installation method, the boot scripts on the image automatically resize the rootfs partition to fit the SD card on the first boot.

~~Use this as~~ a template:

* To generate a default <code>/etc/nixos/configuration.nix</code> file, run <code>sudo nixos-generate-config</code>.

* You can also use an existing template:

{{file|/etc/nixos/configuration.nix|nix|<nowiki>

{ config, pkgs, lib, ... }:
