Systemd ordering: after multi-user.target before getty.target?

I have an installer which I turned into a systemd service it needs, * networking.target to be online * multi-user.target to be online I want my installer service to run after the above but **before** getty.target and console-getty.service. This is because I do not want the console to spam for a login before the installer is complete. However, my distro (Centos 7) specifies a dependency on multi-user.target to getty.target, /usr/lib/systemd/system/multi-user.target.wants/getty.target This means I can't put my service between the two, because my service will then be * Dependent on multi-user.target * Which is dependent on getty.target * While my service is specified to BEFORE getty.target, and AFTER multi-user.target What should I do given my needs here? Is there a way to do this by customizing /etc without mucking with /usr/lib so it's safe with the distro?
