They are indeed stored, as Jake said, which means you should not be adding
roles or caps on init, but rather as a one-off like activation (then remove
on deactivation). OR, you can do that Unfiltered MU does, and do it on init,
but avoid writing to the database. (Cheap hack, but gets the job done.)

That said, there is a $wp_user_roles global that can be used to hard-code
roles and capabilities in wp-config (and the DB would be passed). I know for
example this is what wp.com uses, so you should probably be aware of that as
well.
