I'm not sure mv(1) behaves like that on Linux nowadays:

$ strace mv foo bar

...
stat("bar", 0x7fffffffdd40)             = -1 ENOENT (No such file or directory)
lstat("foo", {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
lstat("bar", 0x7fffffffda10)            = -1 ENOENT (No such file or directory)
rename("foo", "bar")                    = 0
...

But apps are certainly allowed to do link+unlink, and it should work reliably (ie. for a case-insensitive mount the link call should fail with EEXIST).
