I assume the first line is debug output verifying that DCL received the command line?

How much has needed to change from the initial plan outlined in http://www.vmssoftware.com/pdfs/State_of_Port_20171006.pdf ?

I was expecting to see another disk device besides DMM0.  I didn't think DMM0 was to be the "system" disk, only the boot(strap) disk, used only by the Boot Manager and the Dump Kernel. Or will the DM device be writable and allow multiple system roots to be defined on it?  I envisioned that is would be more like booting from a CD installation disk, and that at some point, after the real system disk was mounted, that control would be transferred to the non-MD system disk.  However, reading the 20171006 State of the Port, that isn't really addressed, or if it is, I missed it when scanning through it.

I'm looking forward to a technical update after the first boot has happened.   Hopefully, VSI will have a Technical Webinar, perhaps with some demo
