Looks like they've dropped the generic rpms... so it gets a bit messy (and huge) to manage it in CB/files1 as it's about 500 meg of rpms per OS type... 32-bit, 64-bit, multiplied by el5, el6, el7, so that's roughly 3 gig per version (not impossible, but quite a lot of data)
We'll have to decide if we'll move CB to use their "MySQL yum repo", which might make life easier anyway... or just download straight from a MySQL mirror via CB, instead of files.da (which might have a tendency to break if they change mirror names).
So, not sure yet.
