The patch is currently being discussed on LKML and hopefully will be included
in mainline in some form in the future. Note that booting from the livecd has
to do a lot of work before anything is output to the console, so if the drive
is still busy don't assume the boot has hanged

Note: This feature is INCOMPLETE. Moreover, when runEfibootmgr is true it will
MODIFY NVRAM and, on Apple systems, possibly brick your firmware. PLEASE be
careful while further testing is performed
