I installed Parabola in an encrypted / with f2fs and btrfs in /boot
Grub doesn't support F2FS you will need syslinux Here is the tutorial I used: https://www.youtube.com/watch?v=AQxk1uUQ-pQ The video is pretty straightforward.Don't be afraid of Parabola it works great and it hasn't give me a problem in over 6 months.
If you decide to use this tutorial just remember to update syslinux every time you update the kernel. But you will see how to do it in the tutorial.
