That is true in concept, although fuzzy in the details. In 1973, S/370
virtual  had just been delivered, there was DOS/VS (born  of DOS), VS1
(first born of MFT), VS2 R1 (or SVS - first born of MVT). MVS came a
few years later. [No one talks about FS any more...]

In the late 1970s, IBM made a public commitment to resolve any
problems related to security/denial of service/etc ... in MVS. Now MVS
begat OS/390, which begat z/OS etc etc. It was the commitment to cure
security holes which made the difference.
