	Sure.  I went to the svn book, this part:

http://chestofbooks.com/computers/revision-control/subversion-svn/Managing-Repository-UUIDs-Reposadmin-Maint-Uuids.html

	My server's running 1.4.4, so the 1.5 command 'svnadmin setuuid
/var/svn/repos' will not work.  Instead I used the second method.  I
created a shell function to generate the uuid:

  uu() {
      echo SVN-fs-dump-format-version: 2;
      echo;
      echo -n "UUID: ";
      uuidgen;
  }

I then used that with the second method to update my repositories:

  # uu | svnadmin load --force-uuid /var/svn/repos

Obviously I replaced '/var/svn/repos' with my own repository paths.
	It's nice that Subversion uses standard UUIDs.  It works
directly with  uuidgen.
