According to the OpenShift template and the upgrade description, the system-resque dc is already not being used in 2.4.
However, the following documentations still include the system-resque.
Please remove the references to system-resque from the above documentation.
Suggesting to add a note to the Release Note about the removal of system-resque
Also would like to know how to manage jobs which were being managed by the system-resque in 2.3?
