   \begin{exe} {dnf or yum Required}

      \begin{redhatfamilybox}
         To do these labs you need to have access to a
         system that is \textbf{dnf}-based, such as
         \textbf{RHEL/CentOS} or \textbf{Fedora}.  On
         \textbf{RHEL/CentOS 7} you should be able to substitute
         \textbf{yum} for \textbf{dnf} in the following
         commands and solution suggestions, as \textbf{dnf} is
         backwards compatible.
