## Remote installation: disko and nixos-anywhere
### Remote installation: disko and nixos-anywhere
Install NixOS via SSH everywhere.
There is a separate repository for these steps. Its README can be found here: https://codeberg.org/privacy1st/nixos-anywhere-example/src/template/README.md

### ISO
#### ISO creation
If you are on an architecture other than aarch64, enable emulation: `boot.binfmt.emulatedSystems = [ "aarch64-linux" ];`.

Alternatively to emulating the aarch64 architecture we could also cross compile from e.g. x86 to it. However, this has one big drawback: The binary cache (https://cache.nixos.org/) won't be used. The reason for this is that packages built with cross compilation are (slightly) different from native built ones. Their checksums don't match.
### Default configuration
#### Default configuration
When the Raspberry Pi is booted, run `nixos-generate-config` to generate the default `configuration.nix` and `hardware-configuration.nix` files.
A slightly modified config can be found in [./hosts/pi3bplus/](./hosts/pi3bplus/)

### Apply modified configuration
#### Apply modified configuration
The Rapberry Pi 3B+ has only 1GB RAM, which is not enough for `nixos-rebuild`. It is recommended to create and activate a SWAP file first: https://wiki.archlinux.org/title/swap#Swap_file_creation

**TODO**: The EFI menu was working. But I got many squashfs errors when booting an USB stick with the NixOS installer.
