The Funtoo Linux project has transitioned to "Hobby Mode" and this wiki is now read-only.
ZFS Update
ZFS on Linux-related ebuilds* up to version 0.6.5.7 will soon be unmasked for current builds of Funtoo Linux on amd64 hardware. (i.e. build: funtoo-current, arch: x86-64bit or pure64)
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.
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.
