Snapshot feature on btrfs, possible on zfs?

Hi,

I’ve seen that there is a special treatment for btrfs filesystem. Would’nt be possible to implement the same features for zfs filesystem?

Thank you.

ZFS does not have the necessary (cross-device) reflink support (feature request for ZFSOnLinux is here: https://github.com/zfsonlinux/zfs/issues/405 ), so no.
