SP Week 02 Assignments #3: LFS 11.3 Chapter 06-07

Preparation (IMPORTANT!)

• CHECK if your GitHub Account = UserName = GroupName = Hostname.
• Check the output of script “01-Version-Check.sh”. Make sure, no errors! This includes “version-check.sh” of 2.2. Host System Requirements.
  • bash is the shell in use.
  • sh is a symbolic link to bash.
  • /usr/bin/awk is a symbolic link to gawk.
  • /usr/bin/yacc is a symbolic link to bison or a small script that executes bison.
• Check if you need more SWAP SPACE
• Check if you need to SHRINK and CLEAN your VDI files.

Follow “The Linux From Scratch version 11.3 Book” chapter 6-7

• The Linux From Scratch version 11.3 Book (mirror1) (mirror2) (mirror3)
  • Source code mirrors: (source mirror1) (source mirror2) (source mirror3)
• See also previous version LFS 11.2:
  • Kernotex’s YouTube LFS 11.2 PlayList
  • Kernotex’s Host Linux configuration for LFS Chapter 2.2 - “Host System Requirements”
  • The Kernotex’s Linux From Scratch (LFS) 11.2 Highlights Page (here)

Take Note!

• Make sure when to use:
  • your own account (e.g. “cbkadal”)
  • root account
  • lfs account
• Check your “LFS” and “MAKEFLAGS” environment for all accounts (e.g. “cbkadal”, “root”, “lfs”).

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

• You might want to combine the commands in chapter 7.3-7.4:
  • chroot: ADD line MAKEFLAGS=-jN
    • N = CPU cores

echo "LFS=$LFS NPROC=$(nproc) MAKEFLAGS=$MAKEFLAGS"
sleep 1
mount -v --bind /dev $LFS/dev
mount -v --bind /dev/pts $LFS/dev/pts
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
mount -vt tmpfs tmpfs $LFS/run
if [ -h $LFS/dev/shm ]; then
  mkdir -pv $LFS/$(readlink $LFS/dev/shm)
fi
df /
chroot "$LFS" /usr/bin/env -i   \
    HOME=/root                  \
    TERM="$TERM"                \
    PS1='(lfs chroot) \u:\w\$ ' \
    PATH=/usr/bin:/usr/sbin     \
    MAKEFLAGS=-j$(nproc)        \
    /bin/bash --login

• The FIRST TIME RESULT should be:

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

Generate LFS Ch. 6-7 Report

(root)

• After finishing chapter 7, move:

mv $HOME/lfs-temp-tools-11.3-rc1.tar.xz /var/tmp/

• Don’t delete the lfs-temp-tools-11.3-rc1.tar.xz file until the end of the term.
  • If prompted, you should be able to show that file.

(user)

• Last, run:

cd $HOME/myspwork/WEEK02/
bash 02-SP-WEEK02b.sh
