what does 'lazily-updated" mean?

If we create a hardline that references the "real" location of the file (as a path), and then the "real" location moves, we would like the hard link to be updated to point to the new location of the file so that we don't need to do a full recursive inode lookup on every access. Doing this as part of the move operation would suck, but it's not that expensive to update it following a lookup (basically the same way we do parent backtrace updates).
