Install arch linux with zfs root

Obtain latest ISO from archlinux.org and burn it to an ISO
Boot up and change / size \
1. mount a swap partition
2. mount -o remount,size=16G /run/archiso/cowspace

Add zfs support

curl -s https://archzfs.leibelt.de/media/setup/init | bash

```
zgenhostid -f 0x00bab10c
```

Partition Disk(s)
1. Create EFI partition
```
sgdisk -n "1:1m:+512m" -t "1:ef00" /dev/sda
```
2. I suggest a swap partition large enough to hold RAM (8g) contents if you intend to use hibernate
```
sgdisk -n "2:0:+8g" -t "2:8200" /dev/sda
```
3. Allocate the remainder to the ZFS pool
```
sgdisk -n "3:0:-10m" -t "3:bf00" /dev/sda
