5. Mounting

Before we install the base system we need to mount the devices. First we mount the root system - using the folder /mnt for the temporary mount, then we make folders for /boot/efi and /home .

# mount /dev/sda3 /mnt
# mkdir -p /mnt/boot/efi
# mkdir -p /mnt/home

Verify your folder structure

# find /mnt -type d
/mnt
/mnt/home
/mnt/boot
/mnt/boot/efi

Mount the efi and home partition

# mount /dev/sda1 /mnt/boot/efi
# mount /dev/sda4 /mnt/home

Verify your mounts

# lsblk
