I'm looking at running rEFIt in a lab environment and need to limit the
options available to our students.
At the moment you can disable all options via the config file, but bootable
volumes are still presented. I would like to ideally limit our user to only
being able to select bootable volumes from the internal HDD, not CDs,
External Drives or NetBoot.
If I couldn't disable the choice of these options, password protecting them
would be appreciated.
