Just a guess, but I think Hannah means the following:
NAME
rename - change the name of a file
SYNOPSIS
#include <stdio.h>
int
rename(const char *from, const char *to);
DESCRIPTION
rename() causes the link named from to be renamed as to. If to exists,
it is first removed. Both from and to must be of the same type (that is,
both directories or both non-directories), and must reside on the same
file system.
(...)
[EXDEV] The link named by to and the file named by from are on dif-
ferent logical devices (file systems). Note that this er-
ror code will not be returned if the implementation permits
cross-device links.
In other words, rename("/tmp/a", "/var/tmp/b") is unlikely to work.
