Why not just set the mirrors up that DO have copies as multiple baseurls
to any given repository - then just use the failover mechanism?


Also this putting a yum-arch dummy file in a dir sounds KLUDGY - if your
mirrors are broken and unreliable then you need better mirrors, you
don't add in an ugly 'fix' like that to  yum-arch AND to yum.
