Sorry, this is just getting bad. We need to switch to initializing the board root stage3 style, similar to how the SDK or most any semi-complicated Gentoo install starts. Breaking loops while merging into a clean root is just too complicated. On what this does: util-linux now has a udev *and* a systemd use flag. Since we use systemd they both are effectively the same and pull in the systemd package. This adds support for disabling both flags during the loop breaking procedure.
