VM IMAGE

Debian 11 for Vbox from linuxvmimages.com

Unzip the file then convert vdi to qcow2

qemu-img convert -f vdi -O qcow2 Debian_11.1.0_VBM_LinuxVMImages.COM.vdi lfs.qcow2 

Import this disk image inside libvirt to create new VM. If you don't use qemnu you can directly use the VBox image to import config inside VirtualBox, or for VMware user just use the VMware image directly.

Network

To get an ip addr on the NAT network we need to make sure the interface is the same inside /etc/network/interfaces than the one from ip addr

(Show screenshots here)

User root set up

From debian user connect to root:

sudo su -

Then change root password:

passwd <<< $(echo root; echo root)

Now the root user password is root

Update and requirement

Now run the update and requirements script

sh requirements.sh

Second Disk

This disk will be use to build our linux on it. We just need to create a second disk for qemu and add the hardware to our VM. Depending on which interface you choose for this device you may need to change some things in the script. Make sure the script use the correct device then run it.

sh partition.sh

Sources

Download sources to build our kernel and create repository for them, all version used are from the LFS guide. Zlib had to be update from 1.2.11 to 1.2.12 due to link down.

sh sources.sh

LFS User build environment

We now need to create the environment where we'll build the final product, and prepare a cross-compiler toolchain. As well as our building user which will be lfs.

sh lfs_env.sh

Cross compiling toolchain startup

It's time to compile our toolchain.

sh lfs5.sh | tee lfs5.log

Once lfs5 is done and everything is okay, we can run the second part of the toolchain to build and place gcc and binutilos inside our future system

sh lfs6.sh | tee lfs6.log

Entering chroot

First change ownership from lfs to root as we'll build the next tools for and from root inside our LFS mount.

chown -R root:root $LFS/{usr,lib,var,etc,bin,sbin,tools}
case $(uname -m) in
  x86_64) chown -R root:root $LFS/lib64 ;;
esac

Then we need to enter the chroot environment using our script:

sh chroot.sh

Then we need to create the system directory tree using these following commands: Root level directories:

sh chroot_env.sh

Once your chroot env is set up you can run the lfs7 script to build the essentials tools to your system

sh lfs7.sh | tee lfs7.log
