If a package is excluded in the template and later added by a blueprint
or dependency, anaconda will fail to finish the installation. So remove
the -dracut-config-rescue exclusion and instead remove the rescue
artifacts in %post
Some platforms, like ppc64, require that the /boot partition be present.
It doesn't hurt to have it there on other platforms so instead of trying
to add per-arch kickstart templates just use reqpart --add-boot
everywhere.
Some platforms do not have grub2, and some require other partitions.
Anaconda will add platform specific partitions if the 'reqpart' command
is included, and it will add bootloader specific packages to the list if
they are needed.
This is required to ensure that SELinux is configured properly while
building. It fixes the problem with building tar, and should be
installed in the other image types for consistency.
