OK it's a little annoying when you provide so little information from
the very start about what you're trying to do, and what the setup is,
and now you're not even using a Fedora kernel. It's sorta important
information to say upfront when you're having a problem. I don't
really know what state your system is in now to even have a chance of
reproducing the problem.


When I install kernel-modules-extras, nilfs2 on /home works for me, I
don't have duplicate UUIDs, and boot doesn't fail when trying to mount
home. *shrug*

/dev/sda2 on / type xfs (rw,relatime,seclabel,attr2,inode64,noquota)
/dev/sda3 on /home type nilfs2 (rw,relatime)
/dev/sda1 on /boot type xfs (rw,relatime,seclabel,attr2,inode64,noquota)
