Description of problem:
I think there is a missing boot option on Live media created by livecd-creator:
boot from the system default bootloader. Since the Live media (CDROM or USB key)
created from livecd-creator is not ejected when the system is restarted or shut
down, the user needs to remove it immediately after the system starts up. Else,
the system will boot from the live media.
The option to boot from the system default bootloader would be a nice addition
for advanced users.
