Hi, As per MFC r271563 <http://svnweb.freebsd.org/base?view=revision&revision=271563>: Make the root-on-zfs part of the installer warn a user who booted the installer via UEFI that we do not support booting ZFS via UEFI yet Just wondering why missing zfs support as zfs-boot technique/code is available. It is no offense just if someone could give hint if e.g. UEFI works with GPT and gptzfsboot works with GPT why efi loader cannot utilize code from gtpzfsboot to use zfs boot fs directly. Also if not now approximately when it will support zfs? Or there are so many obstacles on road rather makes mid term workaround to use efi + zfs-root-ufs-boot combo? Thanks.
