    I'm waiting for the btrfs zstd support, it really helps to reduce the size on the root device even if lzo was used.

      I just keep /boot uncompressed on root you can also use: "btrfs fi defragment -r -clzo /boot" and have root mounted with zstd.

        DON'T do it if you use snapshots, otherwise you will get tons of duplication and it will eat all of your free space.

          What about ZFS encryption instead? I would love to see it implemented.

            I avoid it entirely and just load my kernels directly through EUFI

              Systemd's bootctl just works fine if you want a menu

                Looks like very basic support for old Solaris ZFS encryption. That and ZFS compression are the features I'm waiting on.

                For the meantime with GRUB we have to use LUKS on a GRUB-compat ZFS volume for encrypted ZFS /boot. The rest of / can be encrypted with ZFS and the unlock key passed by GRUB.

                If you don't need GRUB then you can use systemd-boot for a 100% ZFS encrypted setup. My system is just old enough that I don't have UEFI to be able to use systemd-boot. I'm looking into using Clover or some other UEFI emulator combined with systemd-boot to get around the GRUB and no UEFI limitations since I don't think GRUB will support advanced ZFS features anytime soon.

                  We're just asking for it.

                    Ideally I just use the EFISTUB boot method if the computer supports it. Don't even bother with a bootloader and use the EFI menu if you want to boot to other installations. There are some strange EFI implementations that don't work with it, and in that case I use systemd-boot. Both of those methods work fine with an encrypted Btrfs root using ZSTD compression. That's how I have my personal computers configured.
