Newer versions of ZFS introduce bug fixes, support for newer kernels, and in some instances, introduce new storage pool features.

Portage will update these packages in the normal fashion through emerge --update @world. Important additional steps will be required for Funtoo Linux installed on a ZFS storage pool.

* The ZFS ebuilds are sys-fs/zfs, sys-fs/zfs-kmod and sys-kernel/spl.

   Important

As best practice, it is strongly recommended that all users backup their data on a regular basis - irrespective of the file system being used. This could be particularly important should something go wrong while modifying or updating a live file system.

   Warning
