In some ways, ZFS on Linux still falls short from the ZFS on Solaris. It is fully ingrained in the Solaris ecosystem, from the boot environment all the way to the graphical user experience. You could even manage your snapshots and more from GNOME. Adding root support for ZFS is a wonderful next step for the Ubuntu distribution. However, I am more intrigued to see what comes next in the integration of ZFS from within the Ubuntu operating environment.
