Summary

In this chapter, you learned:

  • systemctl reboot and systemctl poweroff reboot and power down a system, respectively.

  • systemctl isolate target-name.target switches to a new target at runtime.

  • systemctl get-default and systemctl set-default can be used to query and set the default target.

  • Use rd.break on the kernel command line to interrupt the boot process before control is handed over from the initramfs. The root file system is mounted read-only under /sysroot.

  • The emergency target can be used to diagnose and fix file-system issues.
