This is a huge con, as it becomes much harder to maintain updates. You need to modify you rpmmacros to see both the i386 and x86_64 packages. If you are going to try to compile anything on a multi-lib arch machine, you will need to create separate chroots (or VMs with xen / vmware. etc.) so that you can compile programs that work on either another x86_64 or i386 machine ... as 64 bit and 32bit stuff will be compiled otherwise. You will also have problems getting some i386 software installed over the x86_64 software as there are shared doc files and shared man files the sometimes conflict with each other. Personally ... unless I know for a fact that I will not need any i386 software, I install i386 and not x86_64 distro. If I wanted a workstation, I would not install x86_64. That is just my opinion. -------------- next part -------------- A non-text attachment was scrubbed...
