I currently have archlinux in a pure btrfs installation in three subvolumes I want to try funtoo because it seems great. I have the next subvolumes in / __active/arch-root __active/arch-var __active/home __snapshots/ I have created too __active/funtoo-root and __active/funtoo-var so I want to know how i have to install it using the grub in arch-root? Thanks --haliax
