Shutdown the guest

• Add/create an extra disk with your Hypervisor (VirtualBox or UTM)

VirtualBox

• Visit https://doit.vlsm.org/015.html
  • Crosscheck /dev/sdb (root mode)
  • VirtualDisk Format (root mode)
  • Mounting /mnt/lfs (root mode)
  • Add to /etc/fstab (root mode)

UTM MacOs Silicon

• Visit https://doit.vlsm.org/016.html
  • Crosscheck /dev/vdb (root mode)
  • VirtualDisk Format (root mode)
  • Mounting /mnt/lfs (root mode)
  • Add to /etc/fstab (root mode)

ℼ

Is $LFS == /mnt/lfs ?

• Make sure that LFS is /mnt/lfs
• Execute (root mode):

# CHECKING LFS:
[[ "$LFS/" == "/mnt/lfs/" ]] && echo "ALIAS OK" || echo "XXXXX ALIAS NOT OK XXXXX"
[ -d $LFS/ ]                 && echo "DIR   OK" || echo "XXXXX DIR   NOT OK XXXXX"
# #############

ℼ

STOP/RETURN: if “ALIAS OR DIR IS NOT OK”

Create A New Directory (root mode)

• Directory Name: GitHub-Account (e.g. “cbkadal”).
• Change directory owner/group to your account.
  • You are not cbkadal! Replace cbkadal with your GitHub Account.

IAM="cbkadal"

NEWDISK="/mnt/$IAM/"

if [ -d $NEWDISK ] ; then
   chown -vR  $IAM:$IAM $NEWDISK
   ls -al $NEWDISK
else
   echo "NO $NEWDISK"
fi

ℼ

(root mode)

df $LFS/ /mnt/$IAM/ ; echo""; ls -al /mnt/

NOTE

For UTM MacOs Silicon, replace each device such as /dev/sda with device /dev/vda etc.
