NixOS configuration
How to install
This guide describes how to install this configuration (or any NixOS configuration) with GPT and legacy (BIOS) boot.
If you do not have a wired connection, first set up wifi
wpa_passphrase "SSID" "PSK" | sudo wpa_supplicant -B -i wlp4s0 -c/dev/stdin
Create the partition table (enter the indented lines in the repl).
sudo parted /dev/sdX
mktable GPT
mkpart primary 1MiB 2MiB
mkpart primary 2MiB 500MiB
mkpart primary 500MiB 100%
set 1 bios_grub on
disk_toggle pmbr_boot
quit
Format encrypted partition and open it
sudo cryptsetup luksFormat /dev/sdX3
sudo cryptsetup luksOpen /dev/sdX3 HOSTNAME-pv
Create LVM (replace 8G
with desired swap size)
sudo pvcreate /dev/mapper/HOSTNAME-pv
sudo vgcreate HOSTNAME-vg /dev/mapper/HOSTNAME-pv
sudo lvcreate -L 8G -n swap HOSTNAME-vg
sudo lvcreate -l '100%FREE' -n root HOSTNAME-vg
Hint: If you have to reboot to the installation system later because
something went wrong and you need access to the LVM (but don’t know LVM), do
the following after opening the luks partition: sudo vgchange -ay
Create filesystems
sudo mkfs.ext2 /dev/sdX2
sudo mkfs.ext4 -L root /dev/HOSTNAME-vg/root
sudo mkswap -L swap /dev/HOSTNAME-vg/swap
Mount the file systems and activate swap
sudo mount /dev/HOSTNAME-vg/root /mnt
sudo mkdir /mnt/boot
sudo mount /dev/sdX2 /mnt/boot
sudo swapon /dev/HOSTNAME-vg/swap
Create the configuration (see below) and copy this
repository to your new home directory (e.g. /mnt/home/simon/nixos
).
Add a symlink as the global configuration
sudo mkdir -p /mnt/etc/nixos/
sudo ln -s ../../home/simon/nixos/machines/nunotaba/configuration.nix /mnt/etc/nixos/configuration.nix
Generate hardware configuration and copy hardware configuration to machine configuration
sudo nixos-generate-config --root /mnt/
sudo mv /mnt/etc/nixos/hardware-configuration.nix /mnt/home/simon/nixos/machines/nunotaba/hardware-configuration.nix
sudo ln -s ../../home/simon/nixos/machines/nunotaba/hardware-configuration.nix /mnt/etc/nixos/hardware-configuration.nix
Install NixOS sudo nixos-install --no-root-passwd
Enter the target as a container and set a user password
sudo cp /etc/resolv.conf /mnt/etc/ # see https://github.com/NixOS/nixpkgs/issues/39665
nixos-enter
passwd simon
^D # nixos-enter
sudo rm /mnt/etc/resolv.conf
reboot
How to add new device
- Copy the config from the device that is similar to the new one
- Import profiles/modules you want
- Change settings in
configuration.nix
- Change secrets
