321 | 1 - (debug) - all processes dump core when possible. The core dump is | ||

324 | 2 - (suidsafe) - any binary which normally would not be dumped is dumped | ||

326 | such a dump but not access it directly. For security reasons | ||
327 | core dumps in this mode will not overwrite one another or | ||
