What ever happened to user-mode-linux (UML)? It seems like gVisor takes a similar approach, a "kernel" in userspace handling syscalls. I was playing with UML the other day, a UML kernel is still in Debian's repo and appears roughly up to date[1], but all the documentation I could find on it was many years old and seemed out of date.

- patrickg_zill 8y agoMy experience with UML is very old, but I think that it had a significant impact on performance. About a 50% loss in certain cases, vs running the same applications on the host directly.
