This is probably because it’s still hard to get to work without handcrafting for a particular system, IMO a very telling difference between the old init designs contrary to systemd that handles parallel startups like a champ.
In my experience, booting using single threaded inits (at least in their early stages) actually speeds up the process. The overhead from multithreaded startup on something as simple as an init system can hurt startup performance, especially on older CPUs.
OK thanks apparently OpenRC is a further development of Sysvinit, having many similarities.
