s6-rc 0.6.0.0 and s6-frontend are out!
This new version of s6-rc provides the user with a framework to store and organize their service definition directories, and utilities to craft sets of services that they want to appear in their service database. It is the engine that runs under s6-frontend.
s6-frontend is a user-friendly interface to all the parts of the s6 ecosystem. It provides a single s6 command, that pilots the s6 and s6-rc packages while hiding gritty policy details, and makes the service manager easy to configure and operate. It is the penultimate step before making s6 a full init system that distributions can integrate.
Thanks to 
@nlnet for funding this work!
On to the last step: writing generic essential service definitions that can boot a modern system. Cheers!
