The process used in the previous step is designed to
provide a minimal \baseOS{} configuration. Next, we add additional components
to include resource management client services, NTP support, and
other additional packages to support the default \OHPC{} environment. This
process modifies the base provisioning image and will access the BOS and \OHPC{}
repositories to resolve package install requests.

The instructions below are designed to be copied and pasted all at once into
a terminal.  Alternatively you can run `wwctl image shell \baseos{}`'
to "run" the node image interactively and run the commands one at a time, this
method is recommended.

We begin by installing a few
common base packages:

% begin_ohpc_run
% ohpc_comment_header Add OpenHPC base components to compute image \ref{sec:add_components}
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true,literate={BOSVER}{\baseos{}}1 {\ }{\ }1]

# Install compute node base meta-package
[sms](*\#*) wwctl image exec --build=false BOSVER -- /bin/bash -ex <<- EOF
  dnf -y install epel-release
  dnf -y install ohpc-base-compute
EOF
\end{lstlisting}
% end_ohpc_run

\noindent Now, we can include additional required components to the compute
instance including resource manager client, NTP, and development environment modules support.

Adding packages can be done by entering the image with \texttt{wwctl image shell},
\texttt{wwctl image exec}, or using a CHROOT.
