How stop rpcbind from being started (archlinux, systemd)?

My archlinux's systemd starts rpcbind automatically. What do I have to do to stop systemd to do this? There are no remote filesystems in /etc/fstab. The only thing I found why rpcbind gets started is that is supposedly wanted by multi-user.target but there is no service in the directory. How can I figure out why it is really started?
