I wonder how many more similar problems name spaces have introduced. But wouldn't it be better to place the helper into the name space(s) of the executed process? I guess it would risk breaking some existing set ups, but it seem like the cleanest solution to me. If you want to move the core dump out of the name space you could still use a named pipe or something like that with someone outside listening. That would also fix the net namespace problem you mentioned -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
