Quick updated iso, not really many changes other than I have removed archinstall. Shipping iso with python added near 100Mbs to image. If you really want to testout archinstall live it not that difficult. Given a working network connection open a terminal and run the following:
sudo nano /etc/pacman.d/mirrorlist # uncomment your local servers...
sudo pacman -Syy archinstall # update package lists and install installer
Away you go.
Rest you can find in arch wiki or a quick search of you tube…
Stay safe…
