Build from scratch.
OUI installer has a nice feature, called response file.

If your environments are the same or similar, it will magically install everything without hours of clicking in those screens.

What i would do is :
1. Pop a virtualization solution and install RHEL on it.
Make the network and disk layout as you want it.
2. Take a snapshot of that box.
3. Install the 12c database using clicking via GUI.
4. Save a response file
5. Check if everything is done exactly as you want it.
6. Rollback a snapshot, and reinstall from response file.
7. Examine if desired result is achieved and document it.

ORACLE-BASE - Oracle Universal Installer (OUI) Silent Installations

This will help you in a long run if you initially invest some time in it.

Hacking around with different repositories and rolling back stuff, will only cost you more time in the end.

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris  invokes  the  Solaris  Install  program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

           Minimum physical memory for all installation types

       128 MB

           Minimum physical memory required for windowing system

       384 MB

           Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

           Minimum physical memory for all installation types

       256 MB

           Minimum physical memory required for windowing system

       512 MB

           Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris  exists  only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.
