Union mounts typically have problems - since they tend to want to return
the inode number of the actual file (particularly union filessytems that
let you explicitely select a layer).

Also some other OS (on which you might wish to run the program) have
filesystems which aren't inode based and don't try very hard to make
the value returned by stat unique.
