Well, on SysV the requirement in the "Required-Start:" concept is actually a request to the tool that enables/disables a service (i.e. the chkconfig or update-rcd tool, depending on the distro). It means that it shall enable another service "b" if "a" is to be enabled. Requires= in systemd otoh is something that applies to the actual activation time of a service. The counterpart of "Required-Start:" in systemd concepts would actually be the Also= line in [Install], if you follow what I mean. systemd leaves enabling/disabling of sysv services to chkconfig/update-rcd hence it will not act on that line regarding requirement. It will however act on the ordering, since that's inherently something systemd itself cares about. Hope that makes sense?
