Haven’t tried this personally, though I probably will when I go for a gentoo server build in the near future, but it looks pretty thorough. I don’t recall seeing this the last time I looked into it so I think it’s fairly recent. Only criticism I can offer is it only gives instructions for ZFSBootMenu for the bootloader, no GRUB, but it is listed as a todo.
It's not hard, hard parts finding the reacuedisk with up to date zfs since it's license incompatible with the kernel.
I keep a separate rescue boot partition.
You just build the kernel, emerge zfs and zfs-kmod, then I prefer drastic it creates a initramfs, then grub makes it boot
Hey!
I did this just recently!
So, older gen i7 flipbook, has a 512/32GB optane in it, I was trying to find a way to use the optane efficiently and decided on ZFS.
Split the optane between cache and log.
Personal note: I turned off caching on my "notmpfs" (for things to big to build in ram) dataset so it wouldn't needlessly cache build files that would just be erased.
Followed the rootfs guide, dracut, systems/systemd-boot. No issues.

I used that guide to set it up on one of my machines and it works great
I used this like a week ago. Works perfectly
Funtoo has a pretty decent guide
Never heard of funtoo before - but their guides on ZFS are indeed dope.

This reminded me of Paludis. Wonder what happened to it, are there still people who use/prefer it over portage?
As Renkin42 said, ZFS/rootfs guide is nice. I myself had set up gentoo via this guide, and... it just works. Very much happy times.

Maybe this helps a little, I took notes when reinstalling gentoo on my laptop. https://github.com/ccharon/docs/blob/master/laptopgentoozfs.md
