I was (re?)introduced to Chuck Haley recently and discovered he had a copy of a Bell Labs memo from himself, London, Maranzaro, and Ritchie. They suggest that the path pursued to get UNIX running in/under TSS/370 was the hard way to go.
Oh my.
I mean, I know that OS (and descendants--for those of you without this particular trauma, we mostly mean MVS (now z/OS), but of course there's OS/MFT, OS/MVT, and then OS/MVS) was always trying to kill VM, and we went through similar crap with Linux/390 (and zLinux), which contains code to let it run directly on the iron, even though even production shops are not going to *do* that (OpenSolaris-for-z required VM underneath it; hell, it required a couple new DIAGs we requested).
That actually makes it easy to run zLinux on Hercules, so I'm not complaining, but...it's not how any shop running it as anything other than a curiosity would do it. I mean, OK, I guess you could have a teeny little LPAR but let's face it the LPAR is basically VM.
But TSS was always *also* an also-ran (that is, not OS). It's really weird (to me, anyway) to see it was hostile to VM too.
