Usage case: Extras! So, something like: " The following addtional repositories have been configured: [X] Fedora Extras 6 " in the same screen where you can configure additional repositories; the user can uncheck Extras to only install from their disks. This can be populated by moving over the repo files from fedora-release, and checking what's enabled.
Long-term makes some sense... not really viable given what code we have today
Does this make sense anymore with the extras merge? We probably don't want to enable -source or -debuginfo repos automatically, which really only leaves updates.
So, I'll note that this original bug was actually *solved*, despite Jeremy's comment #1. In the future, yeah, it means updates, which has its own implementation issue.
I think I fixed it after the comment :) At the same time, it's done as a hack with hard-coding URLs instead of using the repo files. But we can probably close this out as that's something to attack another day, time and place... And updates is covered by another bug now as well
