### Ensure all needed packages are installed.
### Consider "yum install -y gettext nss_wraper". There's a typo in nss_wraper
### (should be nss_wrapper), and yum would just ignore it. Thus, a necessary
### package would be missing. With skip_missing_names_on_install, yum will exit
### with 1 exit code and that will stop image building.
