What's going on here with Devuan Excalibur root on ZFS?
I've just installed Devuan Excalibur using mostly the OpenZFS instructions for Debian Trixie, as I did before except with Chimaera (which I then upgraded to Daedalus.) I had a grand old time getting it to boot and started over a couple of times, which is not a big deal because it does not take very long to get to the point where it doesn't boot. I had been using legacy booting and chose to try UEFI, which is working okay now.
