Interesting - I'm not familiar with HP-UX vaults - did they ever catch on in other Unix versions, and did they predate zones in Solaris? How do they compare to Linux containers?
That doesn't refute my statement that BSD pioneered containers with jails, as jails were widely used across multiple BSD versions (though they're oddly missing on macOS) before Linux's container architecture existed.
I had thought IBM did VMs rather than OS-level virtualization (wasn't Gene Amdahl the one who came up with the rules for classically virtualizable architectures?) but I'm not particularly familiar with IBM systems (though I have looked at the 360 instruction set, which has amazingly lasted for more than 50 years.)
