# Foreword
First, this guide does not replace reading the whole LFS book. I highly recommend that you read it at least once. Only then you should use the automation scripts provided here.

This build will be accomplished inside a virtual machine. I'll be using Oracle VirtualBox, but you can use the tool of your personal preference. I'm running an Arch Linux VM, feel free to use your GNU/Linux distribution of choice. Just be sure to install the development tools available (base-devel package on Arch).
This build will be accomplished inside a virtual machine. I'll be using Oracle VirtualBox, but you can use any tool of your personal preference. I'm running an Arch Linux VM, feel free to use your GNU/Linux distribution of choice. Just be sure to install the development tools available (base-devel package on Arch).
My VM has two virtual hard disks: one for the host (Arch Linux itself) and another for building LFS. You could also use a single hard disk with two partitions, that's also up to personal taste. I've decided to use two separate hard disks so I can completely isolate LFS from the host after the build. At the end, you'll be able to create a separate VM and boot from it directly.
The packages needed to build LFS were downloaded from [here](http://ftp.lfs-matrix.net/pub/lfs/lfs-packages/lfs-packages-10.0.tar) (423 MB), other mirrors are available [here](http://linuxfromscratch.org/lfs/download.html) (look for the "LFS HTTP/FTP Sites" section at the bottom, the file you need is lfs-packages-10.0.tar).
