There are a couple other pieces needed before this can be merged. There's a bug in shadow-utils (https://bugzilla.redhat.com/show_bug.cgi?id=1255175) where useradd reads login.defs before calling chroot, and we need it to do the opposite of that, like the other tools do. Also the utilities need to be added to the stage2 in lorax or else cloud people are going to complain at us that creating a users crashes the install, and I haven't written that change yet.
