I found in many cases I need live thumb disk to modify the boot order of UEFI, say, changing back to grub after each macOS update which always puts itself as the first booting. However, efibootmgr is not default included in the live images, even for the current beta1. I have to connect the live system to network, update the repositories and install it with one dependent package before using. But in a situation without network available, it would be a bit inconvenient or having to turn to CentOS CD. So, please consider include it since it is of very small size.
