What Are the Best Linux Init Systems?

What init system does BSD use?

Many Linux® distributions use the SysV init system, whereas FreeBSD uses the traditional BSD-style init(8). Under the BSD-style init(8), there are no run-levels and /etc/inittab does not exist. Instead, startup is controlled by rc(8) scripts.

How do I know my init system?

Determining the init system

In general, you can determine which init system is installed by checking whether the /sbin/init file is a symlink. If it’s not a symlink, then sysvinit is probably in use. If it’s a symlink pointing to /lib/systemd/systemd then systemd is in use.
