Because that works by inode number. The problem being that AFS uses a set
of four 32-bit values, which have to be hashed into a single 32-bit value;
the result is *not* guaranteed to be unique, so ugly things can happen with
programs that rely on unique inode numbers. Such as pwd, and such as
Solaris's ld.so which goes bonkers if two shared libraries on AFS hash to
the same inode number....
