Funny I've been poking with the latest ISO last night in a VM. ZFS on root with mirroring and boot environment is seamless, which to me is a huge enabler for a rolling release with fast update cycle, so I want to try it deeper. Currently on fedora kde spin which has a lot of quircks, with Cosmic coming out soon I'll probably switch.

What quirks did you encounter if I may ask? Was considering this setup.
