What does HackerNews think of rkt?

[Project ended] rkt is a pod-native container engine for Linux. It is composable, secure, and built on standards.

Language: Go

#70 in Go
While quadlets are cool, this just makes me miss the rkt runtime. https://github.com/rkt/rkt It integrated with systemd properly quite a while ago.
Can anyone post an experience using rkt [0]. I'd love an alternative to using Docker for containers, though I'm not sure how well a community has evolved around rkt.
