OpenZFS 2.2-rc1 Brings Linux Container Support, BLAKE3 Checksums, Block Cloning

O_o looks like this is only for FreeBSD and Linux is not included

Only for now, it still needs to get wired up for Linux.

I wonder how it is going to compare to BTRFS' reflinks / offline dedup in terms of performance and limitations.

note: if you boot off the pool and use grub, you most likely won't be able to use any of this stuff...

- upgrade your zfs packages, update your initramfs (if needed) and reboot
- run "zpool get all mypool | grep feature" to see what is enabled and what isn't
- run "zpool set feature@whatever=enabled mypool" to enable stuff

some features need other features, refer to "man zpool-features" for more information.

generally there's a separate boot pool for use with grub that has restricted features.
