I wise man once told me, years ago, that he had unsubscribed from debian-devel because of all the noise. I had thought that rather odd at the time, but have come to appreciate it since.
Like many, I have my opinion in the init system (my choice: sysvinit - it ain't broke, and I already understand it).
However. At the end of the day, does anybody really think Jessie will be released being unable to boot? Unable to shut down? Unable to log people in?
No. That won't happen. It wasn't ever going to happen. No matter which of the init systems was used.
I see no reason we are spending more time talking about this than making Jessie ready to release.
This is a decision that most users will never see.
I've been a DD since the 90s, and in my time I remember transitions and decisions involving:
I can go on deleting threads all day long. I would encourage more of you to do the same.
Because, at the end of the day, it doesn't really matter all that much. It's just a default.
And Jessie will still boot.
