NixOS Configuration files

Setup

sudo nixos-rebuild switch --flake '.#myNixos' or with nix helper nh os switch '.#myNixos'

Bare-setup with BTRFS and LUKS

Adjusted from c8h4:

1. Create GPT partitions

fdisk /dev/sdX

fdisk> g
fdisk> n
# <enter>, <enter>, +512M
# primary partition, number 1, from sector 2048 with size 512MiB
fdisk> n
# <enter>, <enter>, <enter> or add size
# primary partition, number 2
# if necesseary, adjust partition 1 type to EFI System
fdisk> t
fdisk> 1
# write setup
fdisk> w

1.5. Add encryption

cryptsetup -y -v luksFormat /dev/sdX2
cryptsetup open /dev/sdX2 nixos-root

2. Create Filesystems

mkfs.vfat -F32 -n nixos-boot /dev/sdX1
mkfs.btrfs -L nixos /dev/sdX2 # or /dev/mapper/nixos-root if encrypted

3. Create Subvolumens

mount /dev/sdX2 /mnt # or /dev/mapper/nixos-root
btrfs subvolume create /mnt/@
btrfs subv cr /mnt/@home
btrfs subv cr /mnt/@nix
btrfs subv cr /mnt/@log
umount /mnt

4. Mount BTRFS

mount -o noatime,subvol=@ /dev/disk/by-uuid/<uuid> /mnt # or /dev/mapper/nixos-root
mkdir -p /mnt/{boot,home,nix,var/log}
mount /dev/disk/by-uuid/<esp-uuid> /mnt/boot
mount -o subvol=@home /dev/disk/by-uuid/<uuid> /mnt/home
mount -o noatime,compress=zstd,subvol=@nix /dev/disk/by-uuid/<uuid> /mnt/nix
mount -o noatime,compress=zstd,subvol=@log /dev/disk/by-uuid/<uuid> /mnt/var/log

5. Install

nixos-install --flake ".#desktop"
reboot
