Now that all software has been installed, bootscripts have been created, it's time for you to reboot your computer. Shutdown your system with shutdown -r now and reboot into LFS.

One thing remains to be done and that's setting up networking. After you rebooted and finished the next chapter of this book your LFS system is ready for use and you can do with it whatever you want.
