A simple, flexible tool to build an LFS System

LFS Build

Overview

LFS Build is a tool which automatically builds and configures a Linux from Scratch system.

The tool is applicable to LFS version 7.10. The following software is used:

• linux-4.7.2
• glibc-2.24
• gcc-6.2.0
• bash-4.3.30
• grub-2.02

Building your own Linux system from source is a time-consuming process. Here are some real-world examples of how long it may take:

System Specs	Build Time
Intel Core i5, SSD	182m17.485s
Intel Atom, HDD	385m32.365s

Getting started

Build

Create a new virtual machine. Additional disk is automatically created for a new LFS installation

vagrant up

Log in to the VM

vagrant ssh

Build the system. The following command:

• Prepares a new partition which will host the LFS system
• Downloads all required source packages
• Installs packages that will form the toolchain which is used to build the actual system
• Builds the full LFS system
• Installs kernel, bootloader and sets up configuration

bash /vagrant/lfs.sh build

After the build is done you can examine and reconfigure your LFS system. Or just exit and leave the default settings

exit

Gracefully shutdown the VM

vagrant halt

Create a new virtual machine using the lfs disk file box-disk2.vmdk

Obtain the root password

cat ROOT_PASS

Clean up

vagrant destroy
bash lfs.sh clean
rm -f box-disk2.vmdk ROOT_PASS
