'Whether pwntools automatically renames corefiles.
This is useful for two things:
- Prevent corefiles from being overwritten, if ``kernel.core_pattern``
is something simple like ``"core"``.
- Ensure corefiles are generated, if ``kernel.core_pattern`` uses ``apport``,
which refuses to overwrite any existing files.
This only affects corefiles accessed via :attr:`.process.corefile`.
Default value is ``True``.'
