The reason is quite simple: when moving across filesystems the file
must be copied, and GNU mv uses a local variable in the stack as the
buffer, thus the stack must be bigger than the size of the buffer.
Now, i still can't say how big the buffer ist, but i think it is not
bigger than 8K, thus a stack size of 10K should be enough.
