Linux cleanup before turning images into templates for virtual environments

After the OS is installed and prepped there are some cleanup steps needed before turning it into a template.

  • Remove old kernels
  • Remove yum cache
  • Clean out log files
  • Remove device persistencies
  • Clean up MAC and UUID
  • Clean up history and keys
  • I made a sample script that will automate the process. Instead of hosting the script here I’ve moved it to my github.
