I wrote this script today and placed it in AUR. It can show you the way and make it easier to install an archlinux system.
Great! One reason I love Arch Linux is all of the community contributions.
Also, where is your script?
Can you provide some more information?
Your README is not very extensive:
Yet another installation script (for archlinux)
I updated the README, and added a TODO to the git repo. I also rewrote the PKGBUILD. It will be OK now.
