I am following this manual to install Arch Linux from within another Linux distro with the help of an Arch Linux live CD. Here is what I did:

• sudo mount -o loop Downloads/archlinux-2012.11.01-dual.iso arch_iso/
• unsquashfs -d squashfs-root/ arch_iso/arch/x86_64/root-image.fs.sfs
• This results in a directory squashfs-root/ containing one file: root-image.fs

I assume that this is not what I want. I want to see something that looks like a Linux root folder. If I follow these steps: "mount the file system" with mount -B /squashfs-root ${livecd_arch} and mount -t proc /proc ${livecd_arch}/proc, I get error messages like:

mount: mount point /home/me/arch_root//proc does not exist

What am I missing? Thanks!
