Frankly, my experience on mainframes is that UNIX is a stronghold there for a reason. I'd be far more interested in this ecosystem opening up by having strong mainframe vendor support for running Illumos and/or FreeBSD, and less concerned with running Linux. Among other things, Zones are more useful than lxc, and in this type of environment you often need strong kernel support for specialized high-speed interconnects and real-time operations, which Linux only has experimental support for but is integrated well in the UNIX world. I love Linux and what it's done for the world, but UNIX isn't dead for a reason, there are still many things it is superior at.

This is an odd remark - apparently AIX/ESA, the AIX version for mainframe hardware was discontinued "in the late 1990s", roughly the same time when IBM started to invest in Linux.

There was also Amdahl UTS, which was sold to a company UTS Global around 2000 that appears defunct now.

So where is this stronghold of AT&T descendant UNIXes on mainframes then?
Nowhere, but some people call System I/(A/400)/I-Series a mainframe. It's midrange, but people call it what they call it.
Anyway, IBM i and AIX run on the same hardware. They used to be called System I and System P. Now it's just Power Systems.
Maybe thats what he ment.
Or well, come to think of it. There is a UNIX side to z/OS itself.
