- It does coincide, but it is also possible (theoretically) to use a custom
- file system which will address drives larger than 4GB. AFS claims they
- will do this in later versions, but not how. I have seen a couple of
- options discussed, one using block offsets rather than bytes, another using
- two 32 bit offset values to simulate a 64 bit address. I've no idea what
- would happen to the mask value in that case.
