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/sda -- mklabel gpt parted /dev/sda -- mkpart root ext4 512MB -8GB parted /dev/sda -- mkpart ESP fat32 1MB 512MB parted /dev/sda -- set 2 esp on

Formatting¶

mkswap -L swap /dev/sdap2 swapon /dev/sdap2 mkfs.fat -F 32 -n boot /dev/sdap3

ZFS on root partition¶

zpool create -O mountpoint=none rpool /dev/sdap1

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/sdap3 /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 tohead -c 8 /etc/machine-id`

nixos-install --impure --flake github:truxnell/nix-config#<MACHINE_ID>

consider a nixos-enter to import a zpool if required (for NAS) instead of rebooting post-install
