When Debian acquires a properly working s6-rc package, the answer to my question degenerates to "why not?" But for now, for the Debian person who only installs via package, s6-rc is out of the question, so my question was, isn't s6 itself good enough?
Then maybe you should ask Debian instead, "why aren't you packaging s6-rc?" It's literally a distribution's *job* to package software that may be useful to users. And instead, you are bending your mind to try and find justifications for users not to use some software, for the simple reason that it's not packaged by a distribution. That logic is 100% backwards. You want to help users? Package s6-rc for Debian. Also, call out Debian on their prejudice and disingenuous use of policies that prevent people from making correct execline and s6 packages. -- Laurent
