* Easier to add packages to installation list (no need to track dependencies manually). * Allows multiple Yum repositories to be specified and used during bootstrapping. * RPM signatures checking. * Doesn't depend on repository mirror to list directory contents, so it makes less work with the mirror setup. * RPM spec already included, so yumbootstrap installs under Red Hat/CentOS.
