Hello I have installed Centos 5.1 on 64 bit servers, and I see some of the packages have been installed two times, one for i386 and one for 64 bits. I don't know why i386 packages can be installed on 64 bit machine and why they should come together, even some times when I am searching yum repository , I see i386 and x64 packages. shouldn't the search result depend on server architecture ?
