   > Despite the symlink that points these directories to a contract directory, 
the 
[get_dag_directory](https://github.com/apache/airflow/blob/2.9.1/airflow/dag_processing/manager.py#L963)
 resolves this path to its canonical path, which will be different across 
re-syncs. This path get passed all the way to the 
[deactivate_deleted_dags](https://github.com/apache/airflow/blob/2.9.1/airflow/models/dag.py#L3830)
 function in the dag model, by which is used to mark the dag inactive and 
therefore hidden from the UI. The deletion is not happening since the 
processor_subdir value does not match the previously registered 
processor_subdir.
   
   Nice find @TerryYin1777.  👍 
   
   
   > Not fully sure the reason why we need to resolve the dag folder path to 
its canonical. I understand it's not an issue with Airflow itself and probably 
happens only when git-sync is used for dag deployment. But given it's a quite 
widely adopted combination, is it possible to add a configuration like 
GET_DAG_FOLDER_RESOLVE=False so the symlink path is not resolved to its 
canonical path?
   
   
   If possible, let's all try to not add any more configuration options please. 
If this can be solved by not resolving the directory or through some other 
means, that should always work even when not using gitsync. 
   I'm not against configuration but this is one of those options that is going 
to have very subtle impact and will result in footguns if not set correctly, 
and both modes need to work and be tested anyway, meaning more maintenance.
