Thought this was solved with two-way binding - bidirectional links so that
a pointer gets updated whenever the linked element moves.  Or as in OS X
Finder's Aliases (vs Sym/Hard Links) keeping in the link file file both the
higher- and lower-level addresses (the resource name and its inode number).
When a followed Alias mismatches its target name, a search for the univocal
inode gets triggered.
