How to set up a new laptop with NixOS

Set up installation medium

  • Download latest NixOS image: https://nixos.org/nixos/download.html

  • Use lsblk to find the right block device, then copy it over using dd

    $ sudo lsblk
$ sudo dd bs=4M if=${image.iso} of=${/dev/sdx} status=progress oflag=sync

Install NixOS

  • Follow these installation instructions: https://grahamc.com/blog/nixos-on-dell-9560 with the following changes:
    • Activate UEFI before booting into the installation medium
    • Check you're in UEFI mode via ls /sys/firmware/efi/efivars/
    • Create the "key" partition to be 17MiB (16MiB header + 1MiB key): https://askubuntu.com/a/1185737/1011907
    • Just create a user during the installation by recording the output of the following command in hashedPassword: 
      $ mkpasswd -m sha-512
    • If you're doing the installation from a WiFi network with a captive portal, make sure you have a browser installed after reboot so you can log in!
