Just providing a convenient view on the repository. The only write operation you can do through the filesystem is write to the checked out version. Checkin, checkout, branch, label, create new file/directory, rename, link, chmod, etc are all user-space. Also, you can use ClearCase without the filesystem (snapshot view) and get all the same functionality.
