rc.sysinit replacement for systemd for early action

With rhel6 / centos6 I used to set some very early actions (like changing default CPU affinity settings) in rc.sysinit early steps.
Now with rhel7/centos7 and systemd, what would be the right way for doing so?
I was thinking about adding some dedicated service constraint in early target like local-fs-pre.target.
Any comments about this will be welcome.

You would add a new .service file to /etc/systemd/system. ExecStart= would contain your action, while Before= After=, Requires= would help specify another service or target name related to when you wanted the action to run during boot.

- man systemd.unit
- man systemd.service

Yes, this is what I meant by "adding some dedicated service constraint to ... ", I should have written "adding some dedicated service as a constraint to ... ". thanks.
