I won’t comment once again systemd, I think my mind set on the topic and future will tell if I was right or wrong. Still, dislike for the humongous scope self-assigned by systemd does not equate to consider that sysv-rc cannot be improved, it does not mean being stuck to sysv-rc.
Good thing is OpenRC is still being developed (latest release: 7 days ago) and, being portable over BSDs, is very unlikely to follow systemd path. Switching Debian 8.8 from sysv-rc over openrc ( assuming you already got rid of systemd ) is just a matter of installing it:
apt-get install openrc for file in /etc/rc0.d/K*; do s=`basename $(readlink "$file")` ; /etc/init.d/$s stop; done
Then after reboot, removing sysv-rc:
apt-get --purge remove sysv-rc rm -rf /etc/rc*.d /etc/rc.local
You might want then to edit /etc/rc.conf (for instance for LXC containers rc_sys=”lxc” option), check status with rc-status , check services according to runlevels in /etc/runlevels .
