+\t- providing this script with a target partition where system will be installed
+\t- extracting precompiled squashfs system image into the specified parition
+\t- setting up GRUB, BIOS or UEFI mode will be used depending how system was booted
+\tGentooX uses openSUSE-style BTRFS root partition & subvolumes for snapshotting with snapper
+\tGentooX requires minimum of 16GB of space, and use of BTRFS is hardcoded
