Doc Text:
After upgrading the hypervisor on a legacy (non-EFI) machine, the /liveos directory was unmounted, so users could not access the backed up version of the hypervisor. Now, a non-EFI installation reads grub.conf for changes before it unmounts the /liveos directory, so the hypervisor backups are still available after upgrade.
