It is a very elegant implementation of s6
Vocabulary nitpick: no, 66 is not an "implementation of s6".s6 is not a specification. It is a software package. So, there is no other
"implementation of s6" than the s6 software package itself. 66 is a service manager than runs on top of the s6 process supervision suite. It is an implementation of the "service manager" concept. It uses the s6 interface. Just making sure we're using the correct terms. It helps prevent misunderstandings. :) -- Laurent
