- The NixOS installer doesn't do any partitioning or formatting yet,
so you need to that yourself. Use "fdisk", "mkfs.ext2" and "tune2fs".
- Mount the target root device, e.g., under /mnt.

- Do the installation:
$ nixos-installer.sh /dev/TARGET . my-config.nix
$ nixos-installer.sh ROOTDIR . my-config.nix
