Startup Commands

sudo apt install ssh
mkdir ./lfs
sudo mkdir /mnt/lfs

Version Check

sudo apt install build-essential
sudo apt dist-upgrade

cat > version-check.sh << "EOF"

Make executable and run

sudo chmod +x ./version-check.sh
bash version-check.sh

Output from the first ./version-check.sh pass

FIX:

sudo apt install bison binutils gawk texinfo
sudo ln -sf bash /bin/sh

Output after installing all dependencies

Clean version-check.sh

Partitioning Scheme

/dev/sdb needs to be partitioned

lsblk output

Setup Partitions

sudo -i
cfdisk /dev/sdb

cfdisk output

Now select Write and type yes

lsblk after cfdisk

mkfs.ext2 /dev/sdb2 -L LFSBOOT
mkfs.ext4 /dev/sdb3 -L LFSROOT
mkfs.ext4 /dev/sdb4 -L LFSHOME
mkswap /dev/sdb5

Command Outputs

lsblk -f /dev/sdb

/dev/sdb partitioned

Setting $LFS (2.6)

As normal user

exit
echo "export LFS=/mnt/lfs" >> ~/.bashrc
source ~/.bashrc
echo $LFS

As root user

sudo -i
echo "export LFS=/mnt/lfs" >> ~/.bashrc
source ~/.bashrc
echo $LFS

Mounting LFS manually (2.7)

sudo -i
mkdir -pv $LFS
mount -c -t ext4 /dev/sdb3 $LFS
mkdir -v $LFS/home
mount -c -t ext4 /dev/sdb4 $LFS/home
swapon /dev/sdb5

Mount on Boot

nano /etc/fstab

reboot
lsblk
