CodeIgniter 2.0 - you can longer name a controller 'system' out of the box.

This is not a bug, but a change which has come about in the release of CI 2.0.

After spending hours trying to work out why a mod_rewrite (pretty url) would not work on CodeIgniter 2.0 when it did in 1.7.2, I feeled compelled to post. Perhaps this very specific situation it will save someone some time...

It turns out that you can longer name a controller 'system.php'. I don't know the exact details of why the rewrite used to work and doesn't now, and unfortunately don't have the time to spend hacking to work that one out. The .htaccess code in http://codeigniter.com/wiki/mod_rewrite/ mentions that it allows a controller system.php but this appears not to be the case (perhaps it has not been updated (or tested) since the new CI release).

My quick and dirty solution was to rename the systems directory to system_files and update the setting in index.php in the root directory. I needed my controller to be called system.php for legacy support with an old system, so this was the fastest/easiest solution.
