Steve, with all respect, If possible, can you answer question in the end of this message? This is critical question because if you doesn't have answer that mean quick-boot-lvm.patch introduced regression for affected devices without keyboard for no single good reason. You said:
> Nevertheless, this configuration does NOT reliably allow the user to reach the boot menu with the default timeout of 0. However, as I can see this is not the case in practice. Which is why I asked in Comment #10: could you please clarify under which circumstances this configuration does not reliably allow user reach boot menu? ** Changed in: grub2 (Ubuntu) Status: Opinion => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815002 Title: quick-boot-lvm.patch caused regression - menu always appear if root is on Btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1815002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
