[SOLVED] Dual Architecture

I'm staring at http://www.archlinux.org/download/ and wondering what "Dual Architecture" means. Wikipedia gave a general gist of the concept, but I don't understand how that applies to Arch and if I should use that ISO build.

Re: [SOLVED] Dual Architecture

The dual architecture images work on both i686 and x86_64 processors.

Re: [SOLVED] Dual Architecture

correct me if I'm wrong, but it seems that dual architecture would imply that it is optimized for both i686 and x86_64, which means you could have an install that works on both architectures (say if you are making a bootable flash drive for example)  imo, you should probably only use this if you know that that is what you need, because it most likely comes with several libs etc that you won't use on your architecture. (extra bloat)

EDIT: looks like Barracuda beat me too it smile

Re: [SOLVED] Dual Architecture

It simply holds a kernel/initrd and the core packages for both i686 and x86_64, respectively, and you can pick one from the grub menu. So if you only need to install on one computer, you will only need the image for the architecture you chose to install. There is nothing like a "dual architecture" install, although you can run a i686 install on a x86_64 system but not the other way round.

And BTW, Readmes are there to be read

Arch Linux Installation and Live-CDs wrote:

Both come in i686, x86_64 or dual variant. The latter contains both and lets you choose
an architecture at boot.
