**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 ```
