# Instructions and scripts to automate the process of building a LFS system #

[Linux from Scratch](https://www.linuxfromscratch.org/lfs/view/stable-systemd/index.html)

- install host requirements

on debian based systems:

```Console
sudo apt -y install m4 bison texinfo build-essential &&
sudo dpkg-reconfigure dash
```

on rhel based systems:

```Console
sudo dnf -y install gcc g++ make m4 bison byacc patch texinfo
```

- check host requirements

```Console
bash version-check.sh
```

edit **vars.sh** and change the options to suit the desired needs:

- JOBS: parallel CPU threads used for compiling packages
- NETWORKINTERFACE: the name of the network interface which will be configured
  with dhcp
- HOSTNAME: the hostname used for the network configuration
- DOMAIN: the domain name for the network configuration
- KEYMAP: the keyboard layout
- LOCALE: the system locale
- TELNETD: if the telnet server service should to be installed
- PAPERSIZE: the default paper size used by the groff package
- MAKECHECK: to run the checks for each package in addition to the build and
  install process
- TMPASTMPFS: if the mountpoint for /tmp should be set up as tmpfs by systemd

start with the LFS chapters:

- 2.4. Creating a New Partition
- 2.5. Creating a File System on the Partition
- 2.6. Setting The $LFS Variable
- 2.7. Mounting the New Partition
- 3.1. Introduction
- 4.2. Creating a Limited Directory Layout in the LFS Filesystem
- 4.3. Adding the LFS User
- 4.4. Setting Up the Environment

copy the scripts to /mnt/lfs/sources

- as the lfs user from within the sources directory run **chap5-6.sh**

- when prompted logout the lfs user and as the root user from within the sources
directory run **chroot.sh**

- when prompted run **chap7p1.sh** from within the sources directory in the chroot
environment

- when prompted run **chap7p2.sh**, **chap8p1.sh** and **chap8p2.sh**

- optionally run **bash-setup.sh** for a base configuration of the bash shell

continue with the LFS chapters:

- 10.2. Creating the /etc/fstab File
- 10.3. Linux
- 10.4. Using LFS_GRUB to Set Up the Boot Process
- 11.1. The End

if the chroot environment has been exited and needs to be re-entered,
use **re-chroot.sh**
