This will allow the existing THP guide of "do the init script, and maybe also do tuned/ktune (if necessary)" to be simplified back down to just "do the init script or tuned/ktune (as appropriate)".

The RHEL6 method is TBD.

The RHEL7 method will be the following (or substantially similar):

[main]
include=virtual-guest
 
[vm]
transparent_hugepages=never
 
[script]
script=script.sh

#!/bin/sh
 
. /usr/lib/tuned/functions
 
start() {
    echo never > /sys/kernel/mm/transparent_hugepage/defrag
    return 0
}
 
stop() {
    return 0
}
 
process $@
