Hey, Josef! I agree that Kamal is simple, but with capistrano I had no such problems I had with Kamal. I had a couple of conversations with devs from different communities and some of them stuck with Kamal configuration.

PS: Thanks a lot for your book, I've used it when I stuck with Kamal 1, it helped me a lot about a year ago (but there were some issues, not sure that I can remember details).
