ZFS boot+root on Linux is amazing as well. It's kind of sad to see Linux Mint has moved away from supporting this in their installer, but it probably could still be done manually I guess. After upgrade, if something goes wrong? zfs rollback both to a snapshot made just before the upgrade and reboot.

I don't use freebsd full time, only in a VM, but all these things sound positive to me.
