Solaris has had so many cool features, like ZFS or doors. What I liked about ZFS is you coul make snapshot, which is basically the solution to how to treat data files a single, cheap to access unit, yet still use standard apis for file management, great for containerizing apps, making copies for experiments, or shipping stuff. Node.js just received this as a bespoke, app-level feature. But these things are too many to count, and make a ton of sense if you know how filesystems actually work. useful Also copy-on-write, temp overlays.

Sun was a really cool company.
