Creating self contained libraries

As jedd mentioned to you system should never be touched and most of us move the application directory out of the system directory, makes it easier to update when a new CodeIgniter version comes out.

Conversely, for your own change management, are you happy to test changes to your library across all 6 of your apps prior to pushing out changes to this one file? If so, I'd suggest symlinks.

I agree with jedd. If you have several sites running on the same server, all using the same base CI install, you can just as easily have a directory added 'shared' and just symlink across your applications. Now you have a single file to maintain.
