This will save your butt in case you do something foolish and delete everything on it. (I’ve done this). So here’s [...]

So I did some looking around and found atop. In order to get the full benefit of additional per-process statistics from atop, kernel patches are needed that provide the necessary counters. I thought this was a good opportunity to do two things then. Patch a Redhat Enterprise kernel to get full benefit of atop and then recompile the newly patched source into an installable kernel RPM.
