Now that all of the software has been installed, it is time to reboot your computer. However, there are still a few things to check. Here are some suggestions:
Install any firmware needed if the kernel driver for your hardware requires some firmware files to function properly.
Ensure a password is set for the root user.
A review of the following configuration files is also appropriate at this point.
/etc/bashrc
/etc/dircolors
/etc/fstab
/etc/hosts
/etc/inputrc
/etc/profile
/etc/resolv.conf
/etc/vimrc
/root/.bash_profile
/root/.bashrc
Now that we have said that, let's move on to booting our shiny new LFS installation for the first time! First exit from the chroot environment:
logout
Then unmount the virtual file systems:
umount -v $LFS/dev/pts mountpoint -q $LFS/dev/shm && umount -v $LFS/dev/shm umount -v $LFS/dev umount -v $LFS/run umount -v $LFS/proc umount -v $LFS/sys
If multiple partitions were created, unmount the other partitions before unmounting the main one, like this:
umount -v $LFS/home umount -v $LFS
Unmount the LFS file system itself:
umount -v $LFS
Now, reboot the system.
Assuming the GRUB boot loader was set up as outlined earlier, the menu is set to boot LFS r12.2-43-systemd automatically.
When the reboot is complete, the LFS system is ready for use. What you will see is a simple “login: ” prompt. At this point, you can proceed to the BLFS Book where you can add more software to suit your needs.
If your reboot is not successful, it is time to troubleshoot. For hints on solving initial booting problems, see https://www.linuxfromscratch.org/lfs/troubleshooting.html.
