Why are some deamons run out of service and some out of initctl in Ubuntu? Do both tools do the same thing and it is just a matter of personal preference of the user what they will use?

E.g.

sudo service --status-all

vs

sudo initctl list

In my particular instance cron runs out of initctl, and ssh runs out of service. But on Fedora, for example, both of those will be in systemctl.

Some distributions are replacing the legacy System V to manage services. Ubuntu uses upstart while Fedora uses systemd. Generally speaking do the same, but systemd is more different that upstart respect System V. upstart is based in events, whereas systemd try to do aggressive parallelization and manage not only services, but sockets, devices, etc.
