One neat exercise to test our abilities with both the ELF format and ptrace is to design software that can reconstruct a process image back into a working executable.

Extended core file snapshot (ECFS) technology is capable of this and extends the functionality into an innovative forensics and debugging format that is backward compatible with the traditional Linux core files' format.
