Purpose Let’s make a root(/) partition except /boot directory be btrfs. btrfs supports a copy-on-write functionality. For the reason of excepting /boot partition, the Ubuntu document warns against including Grub into btrfs partition. ... As of 11.04, it is possible to use only btrfs file systems with the caveat that grub 'MUST NOT' be installed to the boot sector of the btrfs volume containing /boot. (from [link](https://help.ubuntu.com/community/btrfs)) As a result, I decided to make the /boot partition be separated from the root(/) partition.
