[Bug 1815002] Re: quick-boot-lvm.patch caused regression - menu always appear if root is on Btrfs

[RussianNeuroMancer]

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?

  In my case menu starting to always appear on various devices from
  small tablets to workstations. First time it happened with laptop
  https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/736743/comments/95
  and since then more devices became affected. I not 100% sure, but
  seems like at least one unsuccessfully boot is required to reproduce
  this issue, but maybe I am mistake here and issue starting to happen
  for all Btrfs users.
