A counter point: we have several hundred servers of various makes[*], siz= es and ages -- most OS versions since 4.11 right up to 7.1-p3, typically wit= h 40+ GB HDDs for the system disk (depending on age -- the most recent mach= ines have 160GB) -- all laid out in the all-in-one fashion and we've never see= n the problem described.
