The process is probably quite a bit different from what you did several years ago. The biggest change is that the Arch Installation Framework (AIF) is deprecated in favor of install scripts that bootstrap from an existing system. Still, the installation process is surprisingly easy, and the wiki pages for Talking Arch, the installation guide, and the beginner guide are pretty much all you will need to get a usable Arch system. As for GNOME and Orca, you can just sudo pacman -S xorg gnome gnome-extra and all the packages you need will be pulled in automatically, with the opportunity to select only the packages you want from each group. If you have any further questions, don't hesitate to ask me off-list, as I run Arch primarily and have successfully gotten it installed to a bootable thumb drive using the latest Talking Arch install media. Hope this helps. ~Kyle
