@TomAoki thanks, one additional point: I would not ask OpenZFS to reject the type of code that it already accepts.
To avoid any possible confusion: I mean <https://github.com/openzfs/zfs/commit/6495dafd58b94a44fc9bc966ef47d6bc6916f5b9> as the supposedly offensive example.
I see nothing sloppy or offensive.
The two reviewers and the signatory are eminently well-qualified.

@catavz confirmed:
OpenZFS-encrypted root-on-ZFS is a feature of the installer for Ubuntu 26.04 LTS (Resolute Raccoon).
<https://cdimage.ubuntu.com/daily-live/current/>
Tested in VirtualBox on Kubuntu 25.10.
@ruben condensed:
1. Ubuntu, for simplified OpenZFS-encrypted root-on-ZFS
2. xubuntu-desktop
Whilst I have not tested <https://itsfoss.com/install-xfce-desktop-xubuntu/> @itsfoss (2023) the page is, at a glance, consistent with <https://www.reddit.com/r/Ubuntu/comments/x1urvi/install_xfce_desktop_on_top_on_ubuntu_2204_server/imgtdiw/> (2022).
I chose Ubuntu 25.04 as my base for Kubuntu. I overlooked your comment about Ubuntu (sorry) because the installer made it so simple for me to get root-on-ZFS; and I love simplicity.

Flyer: https://www.nycbug.org/media/2026-04-01_Lucas_Flyer.pdf
progress on my slides for the NYCBUG talk next Wednesday.
Yes, an April Fools' talk. On #openzfs, sort of.
I tend to keep too many #OpenZFS #ZFS boot environments. Case in point, my DNS server:

Still have the original boot environment created six years ago.
