I've made several of these Turners Cubes over the years when I was in the US Air Force, most of the time to teach younger Airmen that you could square a part in a lathe using a 4 jaw chuck. I never used a holding ring nor did I use the hot glue. Each cube was cut from the inside one to the outer one. Sometimes we would heat the cube and freeze a steel ball from a bearing and drop it into the center cube, when everything went back to room temp the steel ball was captured in the smallest cube. This was also a way to teach new guys coming in to a machine shop to think outside of the box to come up with ways to machine parts. You have to understand, that back in the 1970's and in to the late 80's or 90's most of our shops were still using machinery dating back to WWII and we didn't have a lot of tooling like downtown shops or factories had. So we had to come up with ways to use the tooling on hand and make tooling that would work to fix and or make parts for aircraft. It was a real learning experience during those times.

Kernel services for which LSM has inserted hooks and structures to allow access control managed by 3rd party module. SELinux plays an important role during the early stages of system start-up. Because all processes must be labeled with their correct domain, init performs some essential operations early in the boot process to maintain synchronization between labeling and policy enforcement.
