I've determined the cause of this bug in my case: I have a small /boot partition outside of the root filesystem (btrfs). Turns out that that boot partition was not added to the /etc/fstab, so all the kernel upgrading and upgrade-grub operations I was doing were in fact affecting the /boot directory inside the root (btrfs) filesystem, not the actual boop (ext2) partition.
Added the partition to /etc/fstab, cleaned the /boot mountpoint and now all is good in the world. :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273764 Title: Grub ignores options on /etc/default/grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1273764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
