Commits on Aug 6, 2024

  1. Add helper function is_rootfs_uefi() 

    This function searches for the /boot/efi mount point in the /etc/fstab
file of the mount point directory passed as parameter and returns True
if present, False otherwise.

This will allow to check that an existing installation or backup boot
mode matches with the installer boot mode.
