- Removed templates for rhel_5. Due to the latest move of RH
  with regards to CentOS we focus on supporting CentOS/RHEL
  starting with version 6
- Removed unionfs-fuse from package list of netboot images
  because it's not part of the medias. If you need the support
  add the package in the system image XML as follows:

  <package name="unionfs-fuse" bootinclude="true"/>
