I haven't tried this yet but supposedly the Ubuntu installer can setup ZFS on root for a very basic[1] install. (i.e: No redundancy, and no encryption. The former one could trivially add after the fact by attaching a mirror & doing a scrub. The latter you could also do post-install w/ some zfs send+recv shenanigans, and maybe some initramfs changes.) I do use the Ubuntu live image pretty regularly when I need to import zpools in a preboot environment and it works great. In general it's not my favorite distro - but I'm happy to see they're doing some of the leg work to bring ZFS to a wider audience.
