You ask for trouble. A lot of trouble. If you try to update the root, as a result you will get complete insanity (many obstacles, "restored" files, etc.). Also, how do you copy the metadata of a single file? SVN metadata is stored in the .svn folder, which is located in the directory. You may be able to update and commit individual directories that have not been changed (i.e. the directory itself has been moved or renamed, but all its children are exactly the same as in the repo). Again, you cannot. This is dangerous.
