I have before me the "UNIX Programmers Manual, Volume 1, 7th Edition (Revised
and Expanded Version)" which says:
If file1 and file2 lie on different file systems, mv must copy the
file and delete the original. In this case the owner name becomes
that of the copying process and any linking relationship with other
files is lost.
Note that mv did, however, copy the file. (And no, it didn't print any
error message.) Granted, because I am too lazy to hunt down my 6th Edition
manual set, I can't prove this wasn't added to mv(1) (or MV(I)) for
7th Edition and thus could be considered "new" by someone who got their start
on 6th Edition (like me), I really think that's stretching the point.
The message is *useless* because it doesn't allow you to correct the error
(the original file is long gone). It might as well be a random koan.
