For dwarf debug info, an executable normally either contains the debug info, or it is stripped out. To reduce the storage needed (slightly) for the debug info kept separately from the released, stripped binaries, one can choose to only copy the debug data from the original executable (essentially the reverse of the strip operation), producing a file with only debug info. When copying the debug data from an executable with GNU objcopy, the build id and debug directory need to reside in a separate section, as this will be kept while the rest of the .rdata section is removed.
