svnadmin create — Create a new, empty repository.
Create a new, empty repository at the path provided.
              If the provided directory does not exist, it will be
              created for
              you.[69]  As of
              Subversion 1.2, svnadmin creates new
              repositories with the
              FSFS filesystem backend by
              default.
While svnadmin create will create
              the base directory for a new repository, it will not
              create intermediate directories.  For example, if you
              have an empty directory named
              /var/svn, creating
              /var/svn/repos will work, while
              attempting to create
              /var/svn/subdirectory/repos will
              fail with an error.  Also, keep in mind that, depending
              on where on your system you are creating your
              repository, you might need to run svnadmin
              create as a user with elevated privileges
              (such as the root user).
Creating a new repository is this easy:
$ cd /var/svn $ svnadmin create repos $
In Subversion 1.0, a Berkeley DB repository is always
            created.  In Subversion 1.1, a Berkeley DB repository is
            the default repository type, but an FSFS repository can be
            created using the --fs-type
            option:
$ cd /var/svn $ svnadmin create repos --fs-type fsfs $
