Welcome Hyperbola, another LTS libre system

I have just cloned my Parabola system into another partition, for downgrading to Hyperbola, with kernel panic as final and only issue up to now, that Hyperbola is LTS like Trisquel unlike Parabola, but pacman as package manager like Parabola unlike Trisquel.
After this clone before your downgrade, check and update the UUID in /etc/fstab of that partition you need to downgrade to Hyperbola according to gparted, after refreshing this UUID using tune2fs, and dnt touch one you need to remain it as Parabola.
