The file /etc/iscsi/initiatorname.iscsi is not generated by default in latest OCP 4.18(osImage: Red Hat Enterprise Linux CoreOS 418.94.202410160106-0):
sh-5.1# ls /etc/iscsi/
iscsid.conf

As discussed in https://redhat-internal.slack.com/archives/C999USB0D/p1729215335751809, the iscsi-init.service gets pulled in by iscsi.service when it starts because iscsi.service has Requires=iscsid.socket iscsi-init.service, but the service is not enabled by default, RHCOS should enable the replacement service or ensure the file exist to avoid regressions, it might break some 3rd CSI drivers from storage scope.
