    Description

      http://docs.mongodb.org/manual/reference/transparent-huge-pages/

      This page suggests disabling THP in /etc/rc.local. However, when mongod is started from an init service, this will usually be earlier in the boot process than /etc/rc.local. This means that THP will still be active when mongod starts, resulting in startup warnings that will no longer be applicable once /etc/rc.local has run.

      It would be useful if there was another, more reliable, way of generically disabling THP that doesn't have this problem.
