Boot Install Media

Partition the Drive

disko -- --mode disko /usb/disko/[system].nix

Manual Interventions

Disko does not manage raid arrays on purpose. Running the above command would wipe data.

Magrathea

mkfs.btrfs -m raid10 -d raid10 /dev/sdW /dev/sdX /dev/sdY /dev/sdZ
mkdir -p /storage
mount /dev/sdW /storage
cd /storage
btrfs subvolume create @media
btrfs subvolume create @snaps
cd ..
umount /storage

Serenity

mkfs.btrfs -m raid1 -d raid1 /dev/sdY /dev/sdZ
mkdir -p /storage
mount /dev/sdW /storage
cd /storage
btrfs subvolume create @media
btrfs subvolume create @snaps
cd ..
umount /storage

Setup the Config Folder

Generate the default config (Just to get hardware config)

nixos-generate-config --root /mnt

Install the configuration

mkdir /mnt/nix/config
git clone https://github.com/kaldyr/nixos /mnt/nix/config

Merge the generated hardware config

• Make sure the correct graphics drivers are listed
• Make sure the filesystems are correct
• Make sure the state version is correct in system and home manager

Install or Generate Private Keys

• Drop the keys in the /mnt system for system and user
• Generate public keys and user sops key
• If generating new keys, add them into the .sops.yaml and sops updatekeys secrets.yaml

Build the Base System

cd /mnt
nixos-install --no-root-password --flake /mnt/nix/config#[machine]
nixos-enter

Manual Interventions

Samba

sudo smbpasswd -a USERNAME

Reboot into the New System
