a timocracy of one

Like running Edge rails with an svn:externals in your vendors folder, but don’t feeling like always having to stop right in the middle of development to bring your code up to speed because you ran an svn update in your root, and the core team committed something that broke it? Just use the revision flag in your externals property.

rails -r6414 http://dev.rubyonrails.org/svn/rails/trunk

Now svn pedit to bring it up to whatever revision you want (or drop it all together to run at HEAD again).
