yep, it will not change file permissions and ownership, if it already 
exists and is the correct node... we can also create a config flag, 
which changes the goto. You may look at the whole code.

What I also wish is a flag for the DB, which indicates that the file 
already existed and should not be removed with the "remove" ACTION.
