Strange that you say that, since make install does the following:

  ( cd $(DESTDIR)$(pkgsysconfdir)/system/getty.target.wants && \
    rm -f getty at tty1.service && \
    $(LN_S) $(systemunitdir)/getty at .service getty at tty1.service )

See line 3128ish on git master. This is absolutely something that we (Arch
Linux) inherit from upstream.
