#206821 — Installing Debian root on ZFS mirror NetBoot

Hello.

I know that ZFS is not well supported as MD raids. All I've found on internet on installing Debian on ZFS is using a live disk.

My goal is to boot from network and install Debian root on ZFS raid mirror. I can do this using MD raid. I am searching for suggestions of how to 
enable ZFS during installing from network and partition disks using ZFS.

Any suggestion and ideas a welcome.

I migrated my SOHO file server to FreeBSD specifically for ZFS.  While 
FreeBSD rocks as a server OS, I find that graphical desktops are better 
on Debian.  On Debian, I use BTRFS.  I also use only one device for the 
system drive, and keep it small (16 GB SSD and USB flash drives) to 
facilitate taking, storing, and restoring images.

Hello.

I read this guide, but this implies to have a separate MD raid on disk. It is not fully /boot on ZFS.

Erm, this guide walks you through the process of getting / root on ZFS,
though it does make you do a little extra legwork to set up a Z-RAID.
I've followed this guide myself for an encrypted ZFS setup on Debian
with my Laptop.

You are aware that ZFS does not use traditional MDADM, but rather
integrates the RAID functionality directly into the file system, right?

Yes, I know. In 2.2 is mentioned to partition disks. And in 2.3 ZFS pool is created from partitions, not using full disks. And this is confusing me. 
Why create additional partitions not managed by ZFS?

Because you cannot boot from GPT drive unless you have:

- ef02 type partition for EFI
- ef00 type partition for BIOS

And, unlike its Solaris counterpart, ZOL's /sbin/zpool does not label disk by itself.
