LFS (Linux From Scratch) is the most popular tool to create customized Linux distributions from source. Creating your own Linux distribution may include some advantages (and disadvantages too). Among advantages you will learn a lot on Linux by creating your own Linux distribution. You will know how Linux modules interact and how to customize the system.
The operating size is also an advantage depending on your hardware resources or the use you want to give the system. On their website LFS developers say the created a web server to work with Apache on 5 mb size. Together with Gentoo Linux, Linux From Scratch is the most flexible way to setup a Linux system. Building it is pretty simple and the process is described step by step, below I will only show the initial steps to portray an idea of the difficulty and a link to the official documentation showing from the building stage.
To get started with Linux From Scratch you need to create first a partition (minimum 3 GB due compilation process), it is also recommendable to create a swap partition or to share your existing one (for instructions on partitioning check Partitioning hard disks under Debian/Ubuntu and resizing partitions).
Once you created the partition create the $LFS variable by running:
Scratch is a free programming language and online community where you can create your own interactive stories, games, and animations.

This is a live recording showing in real time (there are no cuts made from the recording) how it is possible to. Jul 13, 2017 Of course, it won't stop us from starting the installation through the live environment, and it should work in most cases. If, however, we are more interested in creating a Linux installation USB than a Linux Live USB and don't care about multiboot, UNetbootin or Rufus are better choices. How to create a Linux installation CD / DVD.
You can check it by running:
Then mount the partition:
Note: replace <sdX> for your partition.
Then run for the swap partition:
You’ll need to download packages to a specific directory called LFS/sources, to create the directory run:
Make it writable and sticky:
Download and save within the directory all packages from http://www.linuxfromscratch.org/lfs/view/6.6/chapter03/packages.html

Then you can save the tools to start building your linux distribution following the steps at http://www.linuxfromscratch.org/lfs/view/6.6/chapter05/introduction.html
After finishing change the tools directory ownership by running:
The official documentation to build your distribution, prepare the kernel and base software can be found here. It is a sequence of steps you need to create a customized distribution. The steps are to prepare Virtual Kernel File Systems, Package Management, Entering the Chroot Environment, Creating Directories, Creating Essential Files and Symlinks, installing additional software listed hereStripping Again and Cleaning Up.
To start customizing the system visit the chapters:
Finally install GRUB Using GRUB to Set Up the Boot Process and follow the steps before rebooting for first time
Creating a customized Linux based on Ubuntu is pretty easy, it can be done very fast, it is extremely simple when compared with Linux From Scratch but it is not flexible at all, you’ll be able to add software, customize background and some details but basic customizations like the applications menu edition are not supported.
And add:
