Description of the issue

I was Installing using archinstall on a Intel compute stick (STCK1A32WFC) and I installed without multilib (I almost always use testing repos though) to save space as I only have 32gb of emmc storage as it was installing i noticed when it was syncing the mirrors that it was fetching data from [multilib-testing]

After install everything was fine but [multilib-testing] was infact enabled in /etc/pacman.conf
