Can you use symbolic links to always remove one layer of a directory tree?

Question

Is it possible to use symbolic links or some other method, i.e. a 'virtual directory' or mount, by which the following is achieved, and persistent?

Directory tree A, original

root dir 
|
 +-- dir 1
 |  |  
 |  +-- dir 1.1

Directory tree B, symlinked/virtualised to remove one layer in the tree

root dir 
|
 +-- dir 1.1

I know it can be done as a one time operation by generating symbolic links, but I'm wondering if there's a way to make it persistent, so that if I add a folder 1.2 in directory tree A, it will always show up in the root of directory tree B?

You can use rsync with some script that is ran when new item is created in the first directory. something like rsync --avu delete /dirA /dirB This is helpful: How to sync folders For the script you can use inotify to monitor the create/delete actions in the directory
