Not really. The issue is still present on trusty. If your /boot is a btrfs, grub2 does not know how to save its env.
In order to reproduce: While on grub menu, press c Type: save_env xxx Disabling GRUB_SAVEDEFAULT just disables the feature that needs save_env. It is not a fix. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/736743 Title: environment block not implemented on btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/736743/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
