Ummm, is there anyway around my problem then ?
the problem is that the symlink will always be valid
but the directories that it has pointed to in the past will be deleted.
Whats the reason for resolving the ..'s .'s symlinks etc ?
Thanks

It does much more than that (ex: removing stuff like /./, etc): it is a
minimal access path to the file (starting from the filesystem root).
