@Anjana, can you please change target release to 3.1 if it's going to be fixed in 3.1?

This content looks great, thanks Matt and John

One request, would it be possible to have the URL at the end of the new section
take the the user directly to the relevant section within the Configuration Guide?

> See Setting a Specific Configuration Setting at Runtime for details. 

The current link takes them to the manual but not section 1.6 of the doc.

Are the tunable setting names listed here only in RHCS 3.1 and later?
If so, that should be noted.
