# 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](#how-to-add-new-device)) 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
