As a customer, I expect most of the technical advantages will be basically being a down stream consumer of ZFS. From a developer / maintainer of an OS, Dtrace and ZFS are large technical wins. Part of the overall value proposition of Oxide, is "correctness". You get an OS/Hardware stack that are designed to work together. You get 20 years of cruft thrown out. You get a lot of tooling, API's, etc written in a performant memory safe language (rust). Also you get a really fantastic podcast about the whole process. And as a customer you get a company that understands their stack from driver to VM and has a ton of internal expertise debugging production problems.
