OS Week 09 Assignment #3: Linux From Scratch 12.1 Ch. 6-7

Preparation (IMPORTANT!)

Check file system /mnt/lfs

df | grep lfs

If there is no "/mnt/lfs", see here.

Three (3) Accounts

• your own account, e.g., (user cbkadal)
• root account (root)
• lfs account (user lfs)

Check ALL environments for ALL accounts (cbkadal, root, lfs):

echo "LFS=\"$LFS $(df $LFS|tail -1|awk '{print $1,int($2/1000000)"G"}')\" \
     ARCH=$(arch) NPROC=$(nproc) MAKEFLAGS=$MAKEFLAGS"

Follow "The Linux From Scratch version 12.1 Book" chapter 6-7

• VirtualBox (AMD64)
• The Linux From Scratch version 12.1 Book (mirror1) (mirror2) (mirror3)
• UTM/M1 (ARM64/AARCH64)
• The Linux From Scratch ARM64/AARCH64 Book
• COMPARE
  LFS ARM64/AARCH64 is not an official version (KW) and changes frequently. Therefore, it is recommended to use a package similar to the official version of LFS 12.1 (ORI). Because of this, the instructions for the KW version packages often differ from those for the ORI. Since it uses the ORI package, it must sometimes be compiled using the ORI method. Please be careful, especially when working on chapter 8 and explicitly compiling GCC (chapter 8.27).

Take Note!

You might want to combine the commands in chapter 7.2-7.4 (root)

The FIRST TIME chroot RESULT

(lfs chroot) I have no name!:/#

Generate LFS Ch. 6-7 Report

• After finishing chapter 7, move (root):

mv -v $HOME/lfs-temp-tools-*.tar.xz /var/tmp/lfs-temp-tools-12.1.tar.xz

Cross Check

• Cross-check that "lfs-temp-tools-12.1.tar.xz" is in /var/tmp/ (root)
• The file size should be larger than 850 MB.
• Don't delete the lfs-temp-tools-12.1.tar.xz file until the end of the term.
• If prompted, you should be able to show that file.

date;echo $(arch; lscpu|grep -E 'Model name'|tail -1); du -s -h /var/tmp/lfs-temp-*

Last, run (user):

export LFS="/mnt/lfs/"
cd $HOME/mywork/WEEK09/
bash 09_WEEK09.sh

Result/Report

cd $HOME/RESULT/W09/
