The first thing I wanted to try when discovering zfs-on-root was multibooting snapshots and entire different distributions... but all I had was Ubuntu 19.10...22.04 zsys and /etc/grub.d/10_linux_zfs massive script...
Well I wrangled that premature ejaculation into arch and debian and proxmox; bpool & rpool & org.ubuntu.zsys props, built, zsys, and it worked, until it didn't and distro datasets got promiscuos.
I killed that 3 x ssd laptop with fire.
