I was shocked to see the headline of an article in Linux Magazine that the Linux from Scratch project where you can 'roll your own' distro, will no longer be supporting SystemV Init ... just when I was wondering if it would be possible to do such a thing without resorting to having to use the dreaded systemd.
It seems that they simply don't have the Capacities to support it anymore. So, they had to make a Decision. It might be sad but understandable I think. And the Documentation will stay as far as I have read.
