Actually traditional Unix "init" didn't do ALL those things. Most tended 
to have the inittab config file. Even busybox's init has.

I can't think of a pre-systemd init that mounted filesystems, or spawned 
things like syslog/cron. It ran other programs/systems that did most of 
system-bring-up and the process control stuff one of which was SysV 
initialise setup. Which, surprize though this might sound to some 
people, was, at the time, an improvement on the startup setups that had 
been common previously.
