Alpine ZFS Root

Ideally, follow the steps in "Build a custom virt kernel and ISO with ZFS", and use that install to avoid using unnecessary space and building an unnecessarily large kernel (RAM usage). This produces a system that installs in under 90MB.
Boot from Alpine ISO. Login as root (no password). //* Run setup-alpine to set up network/package repositories, hit ctrl+c when you get to the disk prompt
To set up network with DHCP and the first mirror, run the following, or manually use setup-intefaces -r and setup-apkrepos to set something more specifically. Optionally, use set a root password setup-sshd to set up remote console.

setup-interfaces -ra
setup-apkrepos -1c

echo 'root:9' | chpasswd

Existing references I looked at before I went on trial and error until eventually I managed to make it work:

https://gist.github.com/subrezon/b9aa2014343f934fbf69e579ecfc8da8 (the format of this gist copies this one)
https://forum.openwrt.org/t/minimum-ovmf-uefi-folders-and-files-to-boot-openwrt-in-proxmoxve/75824
https://forum.proxmox.com/threads/openwrt-boot.130221/

Note

Although links above were good references to look at so I didn't have to start from scratch, following none of them actually worked for me. Hence, I'm leaving my own note after figuring things out.

My situation:

Instructions for use

Copy/download get_cloud.py to /usr/local/bin of the Proxmox node
Change common variables inside the script
chmod +x /usr/local/bin/get_cloud.py
Copy and edit the xxx.service and xxx.timer into the folder /etc/systemd/system. Adjust the contents as appropriate (xxx can be any string, provided that the names of the SystemD unit (xxx.service) and the timer (xxx.timer) is the same. The above files are provided as an example only)
systemctl daemon-reload
systemctl enable xxx.timer && systemctl start xxx.timer
To download and import the cloud image right away, run systemctl start xxx.service. You don't have to wait for the service to finish and can back out immediately by pressing Ctrl+C.
To view the output of the service run journalctl -u xxx.service
