I'm much surprised why hardlink shouldn't work.

I used the `stat' command on a file that's both in snapshot and (uchanged) in 
current filesystem state and both inode and device fields (st_ino and st_dev) 
are the same. Thus I don't get why Linux would consider that a cross-device 
hardlink. After all, it's the same filesystem, just different views of it. 
Perhaps Linux' VFS is to blame...
