[Bug 1258597] Re: [Patch] Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ All Ubuntu users.
+ 
+ [Test case]
+ Run 'sudo update-grub'. The message is shown at the beginning.
+ 
+ [Regression potential]
+ Changes to the default config options may adversely impact boot behavior for the systems. Systems could start to always show the grub menu, or it may become hard to reach the menu when it was otherwise reachable due to the changes in timeout behavior. Any changes to the behavior of the boot menu timeout / default grub options should be looked at with suspicion.

  When running update-grub I am getting the following message:
  
  Warning: Setting GRUB_TIMEOUT to a non-zero value when
  GRUB_HIDDEN_TIMEOUT is set is no longer supported.
  
  $ sudo update-grub
