--- deprecations: - The ``DIB_YUMCHROOT_USE_CACHE`` variable has been removed and the Fedora and CentOS ``-minimal`` initial chroot will always be created by the package manager. The default creation of a chroot tarball is stopped for these elements. This unused option was unsafe; there is no guarantee that the base system will not change even between runs. Getting the package manager to reuse the cache for the initial chroot install is future work.
