Canonical is considering a significant reduction in the features of the signed GRUB bootloader for the upcoming Ubuntu 26.10 release. This move, motivated by security needs, could lead to the elimination of support for several file systems and volume management technologies.

Proposal Details

Specifically, there is talk of abandoning support for XFS, ZFS, Btrfs, LVM, md-raid (except RAID1), and disks encrypted with LUKS. The idea is to simplify the bootloader, reducing the attack surface and potential vulnerabilities.

Implications

The removal of these features could impact users who use advanced storage configurations. However, Canonical seems intent on prioritizing the security of the operating system, even at the cost of limiting compatibility with some existing configurations.
