marshalljmiller commented 5 years ago

added targets and scripts to use an existing install iso to re-roll a new one with updated packages and kickstart. this must not be used for production builds because the installation (anaconda) environment and build/version information does not get updated. to use copy an existing install iso to shell.iso and run make VARIANT-inst-iso-fast
