Explicación Oficial / Explicaciones de la Comunidad
In SysV init, runlevel 6 is designated for rebooting the system, which can be triggered by telinit 6. The shutdown -r now command is the standard way to initiate an immediate reboot. telinit 0 is used for poweroff, and shutdown -k only sends a warning message without acting.
