So, for each open directory, the shadowfs would remember the steps taken to get there? That could work. If the user: 1. makes a directory ~/1 and a shadowfs ~/shadow which uses it 2. makes a directory ~/1/foo 3. changes directory to ~/shadowfs/foo 4. renames ~/1/foo to ~/1/bar 5. ls then the shadowfs tries to find ~/1/foo, and because it doesn't exist, the user gets ENOENT. This sounds reasonable. If the user then makes another directory ~/1/foo, the current directory starts referring to that instead, and ls works again. ENOENT on missing directories isn't the only possible way: the shadowfs could instead give the user an empty (except . and ..) directory so that he can at least "cd ..". Would that be better?
