This site contains a link to a build arch linux including the archzfs kernel.
The arch linux iso file is created by using the arch-linux-live-cd-iso-with-zfs build script.
The last build date of the iso is available here
The latest iso can be downloaded here.
The latest iso.sha512sum can be downloaded here.
Once you've downloaded and booted a running archios with OpenZFS, you want to setup the basic system.
Here you will find a two step configuration and installation script.
With that you will get a basic archlinux with zfsbootmenu in "no time".
If you've just started a regular archiso but need quickly zfs support, you can run the following code to add instant OpenZFS support.
curl -s https://archzfs.leibelt.de/media/setup/init | bash
