There are a couple of issues around REX and installation
 - The host configuration guide states that REX is enabled by defautl which it is not. https://access.redhat.com/documentation/en/red-hat-satellite/6.2/single/host-configuration-guide#chap-Host_Configuration_Guide-Running_Remote_Jobs_on_Satellite_Hosts
 The host configuration guide does not have a section on enabling REX.
 There is no link from the install guide to the host configuration guide for setting up additional services.
Assigning to Charles for review.
Charles - looks like we will need to change the description at the start of the chapter, add a short procedure (one step?) on how to enable remote execution, then add a link to this chapter from the Installation Guide to help bring it together.
We will need to check what the command is to enable REX, but my assumption at current is that it would be something similar to that for SCAP, which is as follows -
"# satellite-installer --enable-foreman-plugin-openscap"
The content is now live on the customer portal.
There have been changes made to the host configuration guide detailing how to enable remote execution on Capsule Server. https://access.redhat.com/documentation/en-us/red_hat_satellite/6.2/html/host_configuration_guide/chap-host_configuration_guide-running_remote_jobs_on_satellite_hosts
The installation guide now links to the Host configuration guide. https://access.redhat.com/documentation/en-us/red_hat_satellite/6.2/html/installation_guide/installing_capsule_server#Enabling_Remote_Execution_on_Capsule_Server
