If you are using sccKit 1.3.0, you will notice that Linux boots much faster on all cores. You will also notice that this optimization makes use of a premerged file and does not call sccMerge as the previous sccKit did. Hence, you will not see the familiar files in /tmp/sccKit_username that you used to.
Sometimes looking at the files created by sccMerge can be useful, especially if you want to customize them for your own use. If you choose to boot on less than 48 cores, you will see the /tmp/sccKit_username/obj directory and its contents created.
