IMPORTANT NOTES:
----------------
The 00-rhsm script is specific to RHEL6. If you use the REG\_ variables to
use with RHEL7, you do not need to set any DIB_RHSM variables. The scripts
named with "rhel-registration" have not been developed or tested for RHEL6.
For information on building RHEL6 images, please see the rhel element README.
Environment Variables For Image Creation

The 01-module-configuration script is specific to RHEL8. RHEL8 includes
various versions of software which can be selected during installation, some

Environment Variables for Module Selection during Image Creation
----------------------------------------------------------------
The following environment variable is used to select module streams to be
enabled during an image build on RHEL8. Any existing stream for the given
module is first disabled prior to enabling the specified stream.
#### DIB\_DNF\_MODULE\_STREAMS
This is a space-separated list of module streams to enable prior to any
RPMs being installed.
Image Build Module Selection Example
------------------------------------
When using Train on RHEL8.2, one must select the appropriate virt and
container-tools module streams:
DIB_DNF_MODULE_STREAMS='virt:8.2 container-tools:2.0'
