Canonical is pulling all the stops for Ubuntu 16.04 LTS (Xenial Xerus), and it looks like users will get easy access to ZFS file system. Before you get too excited about the prospect of replacing the current EXT4 files systems, you should know that it will be available only as a tech preview, for the time being.
There is still a lot of work left to be done, and it’s not fully integrated into Ubuntu. The developers still need to add it to the installer, and it will be a long while (if ever) until it is adopted in any sort of default capacity.
The main reason why the Ubuntu devs are looking towards this new file system is because Debian is also supporting it. Since Ubuntu is based on Debian and ZFS seems to be on the rise, it’s only natural for them to try to adopt it.
