Installing Ubuntu 14.04 on a F2FS partition

How can I install Ubuntu 14.04 on a F2FS partition? I created the partition with Gparted but during the installation the Ubuntu installer could not recognize the filesystem on the partition. I heard it is possible to install with the alternative DVD but they say it is only available for Lubuntu.

F2FS is not officially supported bu Ubuntu (bug #1261175) but it should work if you do a normal install, then update initrd to include the f2fs module, copy the root filesystem to a f2fs format partition, re-install grub, and reboot.

Something like (warning: untested):

Create 3 partitions: /boot=ext2 /=ext4 f2fs
Install Ubuntu /boot=ext2 /=ext4, grub on sda
Boot from hard drive
add f2fs to /etc/initramfs-tools/modules
update-initramfs
Boot from CD
mount ext4 / on /mnt/ext4
mount f2fs on /mnt/f2fs
cp -a /mnt/ext4/ /mnt/f2fs/
mount /dev/sda1 /mnt/fsf2/boot
grub-install --root-directory=/mnt/fsf2
poweroff, remove CD, turn on
