According to mattias:
# so /arch/setup are replaced by packstrap correct?

Mostly correct. /arch/setup is replaced by arch-install-scripts, which 
include pacstrap, genfstab and arch-chroot. More info about how to use 
the Arch install scripts to bootstrap an Arch system, either from the 
install media or from an existing system is available from the 
installation guide at
