Ubuntu to Use Signed GRUB2 Bootloader for Secure Boot
A signed version of GRUB2 that will enables Ubuntu to work with Secure Boot devices is to be added to Ubuntu 12.10.
This approach is different to the one Canonical previously announced in which they decide ‘for security reasons’ to use a custom non-GRUB based bootloader – a decision for which they were publicly admonished by the Free Software Foundation.
But, as is developments prerogative, that plan has come unstuck. Ubuntu 12.10 will now use a GRUB2 based bootloader.
