The authors of the os module don't really have any way of knowing the details of what your os/libc combination is going to do. If you're calling os.foo(), you're sort of expected to know what foo() does on your OS. > Also, creating a hard link doesn't seem to work between different file > systems, which may well be relevant to Steve's case.

Again, that's a detail that depends on your particular OS/libc/filesystem implementation. It's not determined by nor knowable by the authors of the os module. -- Grant Edwards grant.b.edwards Yow!
