## NixOS
|
|
|
|
Install instructions for NixOS.
|
|
First open a shell with vim and git:
|
|
|
|
```bash
|
|
nix-shell -p git vim
|
|
```
|
|
|
|
### EXT4
|
|
|
|
```bash
|
|
parted /dev/nvme0n1 -- mklabel gpt
|
|
parted /dev/nvme0n1 -- mkpart ESP fat32 1MB 512MB
|
|
parted /dev/nvme0n1 -- mkpart root ext4 512MB 100%
|
|
parted /dev/nvme0n1 -- set 1 esp on
|
|
|
|
mkfs.fat -F 32 -n BOOT /dev/nvme0n1p1
|
|
mkfs.ext4 -L NixOS /dev/nvme0n1p2
|
|
|
|
mount /dev/disk/by-label/NixOS /mnt
|
|
mkdir -p /mnt/boot
|
|
mount -o umask=077 /dev/disk/by-label/BOOT /mnt/boot
|
|
nixos-generate-config --root /mnt
|
|
```
|
|
|
|
### ZFS
|
|
|
|
First stop the zfs-zed service, and unload the ZFS kernel modules:
|
|
```bash
|
|
systemctl stop zfs-zed
|
|
lsmod | grep zfs | cut -d' ' -f1 | xargs rmmod -f
|
|
```
|
|
|
|
Then add the following to `/etc/nixos/configuration.nix`:
|
|
```bash
|
|
boot.supportedFilesystems = [ "zfs" ];
|
|
```
|
|
|
|
And rebuild the system:
|
|
```bash
|
|
nixos-rebuild switch --upgrade
|
|
```
|
|
|
|
Partition the disk:
|
|
```bash
|
|
parted --script /dev/nvme0n1 -- mklabel gpt mkpart esp fat32 1MiB 512MiB mkpart primary 512MiB 100% set 1 boot on
|
|
```
|
|
|
|
Create an encrypted pool:
|
|
```bash
|
|
zpool create -f -o ashift=12 -O encryption=on -O keyformat=passphrase -O mountpoint=none rpool /dev/nvme0n1p2
|
|
```
|
|
|
|
Create a root partition:
|
|
```bash
|
|
zfs create -o mountpoint=legacy rpool/root
|
|
mkdir -p /mnt
|
|
mount -t zfs rpool/root /mnt
|
|
```
|
|
|
|
And home partition:
|
|
```bash
|
|
zfs create -o mountpoint=legacy -o compression=on rpool/home
|
|
mkdir -p /mnt/home
|
|
mount -t zfs rpool/home /mnt/home
|
|
```
|
|
|
|
Format the boot partition:
|
|
```bash
|
|
mkfs.fat -F 32 -n BOOT /dev/nvme0n1p1
|
|
mkdir -p /mnt/boot
|
|
mount -t vfat /dev/nvme0n1p1 /mnt/boot
|
|
```
|
|
|
|
Generate the configuration:
|
|
```bash
|
|
nixos-generate-config --root /mnt
|
|
```
|
|
|
|
Add the following to /mnt/etc/nixos/configuration.nix:
|
|
```bash
|
|
boot.initrd.supportedFilesystems = [ "zfs" ];
|
|
boot.supportedFilesystems = [ "zfs" ];
|
|
services.zfs.autoScrub.enable = true;
|
|
|
|
networking.hostName = "Aloria";
|
|
networking.hostId = "abcdef01";
|
|
```
|
|
|
|
### Install
|
|
|
|
|
|
Then either clone the repository:
|
|
|
|
```
|
|
git clone https://git.thomasave.be/thomasave/Dotfiles
|
|
sudo nixos-install --impure --flake ./Dotfiles#Aloria
|
|
mv ./Dotfiles /mnt/home/user/.dotfiles
|
|
sudo ln -s /home/user/.dotfiles /mnt/etc/nixos
|
|
```
|
|
|
|
Or install it directly:
|
|
|
|
```
|
|
sudo nixos-install --impure --flake git+https://git.thomasave.be/thomasave/Dotfiles#Aloria
|
|
```
|
|
|
|
### Post-install
|
|
|
|
Clean-up:
|
|
```bash
|
|
umount /mnt/{home,boot}
|
|
umount /mnt
|
|
```
|
|
|
|
If using ZFS:
|
|
```bash
|
|
zpool export -a
|
|
```
