GNU GRUB 2, mostly just
referred to as GRUB these days, is the most widely used boot loader
for x86_64 Linux systems. It supports reading
from a vast selection of filesystems, handles booting modern systems
with UEFI or legacy systems with a BIOS, and even allows users to customize the
“splash” image displayed when a system boots. Alas, all of those features come with
a price; GRUB has had a parade
of security vulnerabilities over the years. To mitigate some of those
problems, Ubuntu
core developer and Canonical employee Julian Andres Klode has proposed removing
a number of features from GRUB in Ubuntu 26.10 to improve GRUB’s
security profile. His proposal has not been met with universal acclaim; many of the
features Klode would like to remove have vocal proponents.
