"Install from an Existing Linux"

Question

All,
My first time installing Arch. I've tried 'Method #3' here:
    https://wiki.archlinux.org/index.php/In … ting_Linux
... and it seems to install fine, however, whereas my target partition is
mounted as '/mnt', as instructed, I note that the root filesystem is created
under '/mnt/archinstall-chroot', which means that when  I reboot to my Arch
partition I won't have a proper root fs, because everything is under that 'archinstall-chroot'
subdirectory. I expect there's an obvious answer to what I'm doing wrong, but
I sure can't find it.  I suppose I could just copy everything but I doubt that's expected.
Looking forward to my first boot :-)

The method 3 downloads a base environment able to execute the arch install scripts. That means that is not the final step on your installation; you have to mount your real partitions under the /mnt dir of that chroot, and then follow the regular procedure.
In another words, is like this:
It creates a directory called archinstall-chroot. If you are on your home, it will be ~/archinstall-chroot
it downloads just enough packages for archinstall script to work(is not your final install!)
It chroots there
You are now on a chroot environment. Now you are supposed to mount /dev/sdaX under the /mnt of that chrooted environment.
And from there, just do the regular steps of the installation guide.
Ok, thanks chris, that answers the main question. It could be made more clear in the wiki, once I've finished, I'll edit it.
