423 | * ino_t and dev_t internally, even if this platform does not | |
424 | * allow files to have 64-bit inums. That's because the | |
425 | * receiver needs to find duplicate (dev,ino) tuples to detect | |
426 | * hardlinks, and it might have files coming from a platform | |
427 | * that has 64-bit inums. | |

430 | * all. | |
431 | * | |

433 | * transfer devices or hardlinks with dev or inum > 2**32 to a machine | |
434 | * with no 64-bit types then you will get an overflow error. Probably | |
435 | * not many people have that combination of machines, and you can | |
436 | * avoid it by not preserving hardlinks or not transferring device | |
437 | * nodes. It's not clear that any other behaviour is better. | |
