Before reading this, I had presumed that sparse files did not overcommit drive space, but apparently, they do. I don't use them regularly and certainly not to "reserve disk space" but I was surprised that you can make sparse files way larger than available free space on the drive. I had assumed they were simply not initialized, but the FS still required <x> amount of free space in case a block is accessed.
