Get hostid

run head -c 8 /etc/machine-id and copy into networking.hostId to ensure ZFS doesnt get borked on reboot

Partitioning

parted /dev/nvme0n1 -- mklabel gpt parted /dev/nvme0n1 -- mkpart root ext4 512MB -8GB parted /dev/nvme0n1 -- mkpart swap linux-swap -8GB 100% parted /dev/nvme0n1 -- mkpart ESP fat32 1MB 512MB parted /dev/nvme0n1 -- set 3 esp on

Formatting

mkswap -L swap /dev/nvme0n1p2 swapon /dev/nvme0n1p2 mkfs.fat -F 32 -n boot /dev/nvme0n1p3

ZFS on root partition

zpool create -O mountpoint=none rpool /dev/nvme0n1p1

zfs create -p -o mountpoint=legacy rpool/local/root

immediate blank snapshot

zfs snapshot rpool/local/root@blank mount -t zfs rpool/local/root /mnt

Boot partition

mkdir /mnt/boot mount /dev/nvme0n1p3 /mnt/boot

#mk nix zfs create -p -o mountpoint=legacy rpool/local/nix mkdir /mnt/nix mount -t zfs rpool/local/nix /mnt/nix

And a dataset for /home: if needed

zfs create -p -o mountpoint=legacy rpool/safe/home mkdir /mnt/home mount -t zfs rpool/safe/home /mnt/home

zfs create -p -o mountpoint=legacy rpool/safe/persist mkdir /mnt/persist mount -t zfs rpool/safe/persist /mnt/persist

Set networking.hostid`` in the nixos config to head -c 8 /etc/machine-id`
