Then wrap yum in a script that tries to update (or install) from tier A, and iff it succeeds run the same update/install command on B. If it finds a newer package there it will install it, but it won't even get to that step unless the package is in A. It's probably going to be better to create very specialized sequences like this by means of wrapping yum in very specialized scripts, rather than trying to add support for every possible mode of installation to yum itself. [Hint: this would be very easy to do wrapping yum inside of perl, which would appeal to my perverse sense of humor...] rgb > > Thanks, > Marc > > -- Robert G.
