CloneZilla process throwing wqrnings

[radl97]

Describe the bug During CloneZilla image ccreation and installation throws a lot of warnings.

It is probably due to some missing umount (poweroff -f)

• For pre-built, image release version: [VM build version]
• For manual build, commit: version-0809
  • I have used autoinstall: yes

There was an LVM and clonezilla related issue.
