# Create a generic HPC image
|
||||
# This script is an example of how to create an HPC image with xCAT stateless.
|
||||
# in this example you may need to change some of the parameters. In the future
|
||||
# we should probably place this in the database...
|
||||
# All good sys admins can reproduce their environments. Creating a stateless
|
||||
# image should be reproducable. Doing this with a script is a good idea.

||||
