The base group was changed to a base meta package and many packages were removed: https://www.archlinux.org/news/base-group-replaced-by-mandatory-base-package-manual-intervention-required/ Therefore, it's necessary to add linux or linux-lts to install a Kernel. Dhcpcd is needed to get an IP after the first reboot. Netctl is needed later when using Vagrant.
