Once upon a time...
In a time oh so very long ago, the arrival of a new Ubuntu release was actually big news.
May I suggest it is now more of a 'Meh' moment.
Sure, the fans will rave on about it but many here we have jumped ship to other distros as they have either outgrown it or got fed up with it.
Mint seems as popular destination for former Ubuntu fans.
I went to the Linux 'dark side' myself and now use CentOS. Still on CentOS 6 so that I can avoid 'systemd' for as long as possible.
As for ZFS, I'm far too old to get excited about a filesystem. I was once very excited about one once upon a time. Well I would be wouldn't I as I wrote my own one as a student back in the 1970's. It was a new Filesystem for RT-11. It worked most of the time still, it was fun for a while. All that bit twiddling deep inside the kernel. Oh, the memories.
