title: Why doesn't git-svn use the Subversion repositories UUID instead of its URL
body: <p>Relocating a git-svn mirror of a Subversion repository isn't trivial:</p>

  <p>So why doesn't git-svn use the repository's UUID instead of its URL in the git-svn-id?  The UUID uniquely identifies the repository, so it seems a natural identifier to use and would handle relocatations much easier.</p>
