# Script to build Kogaion Linux packages in a clean squashfs + overlayfs chroot
# Using predefined targets : kernel.target, libs.target, x11.target, sound.target, artwork.target etc
# Targets are passed as arguments, and will remain private...for now (not all of them are stable yet)
# Author : V3n3RiX @ RogentOS
# Deps : squashfs + overlayfs kernel support
# Todo : add squashfs portage tree && overlays sync && build.git sync && profile setup
# Todo : auto push built packages to repos (maybe, really needed?!?)
