It's either a waste of work, or triggers edge cases in some packages (like coreutils-8.31) where the source file is readonly and cp gets a permission denied error trying to overwrite it with an identical copy of itself. Also while we are at it, make the variable names be something readable, because I could barely tell what this was doing while editing it.
