I use both Grub Legacy and Grub2 on many computers ((K)Ubuntu, OpenSuse, Debian, multiple versions of each).
I can not find a way to password-restrict access to the Grub command line in either version. This allows a passerby to enter "c" to invoke the command-line and then enter commands manually to boot an external device, circumventing BIOS restrictions. Password restricting/locking menu items and removing recovery mode menu items (through the configuration settings) does not impact command-line access, which remains unrestricted. _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org https://lists.gnu.org/mailman/listinfo/bug-grub
