[Bug 1443735] Re: recordfail false positive causes headless servers to hang on boot by default

[Ewan]

Something you may wish to consider in relation to this fix:

Proposal 1)
I noticed the bug description already contains the comment "Maybe a future addition to recognizing $recordfail is to have a warning on the boot menu, but that is outside the scope of this report.". I +1 this for some future update.

Proposal 2) - might be deemed to be low enough risk to implement prior to dev/test/release of proposal 1.
Add the line:
GRUB_RECORDFAIL_TIMEOUT=30
to the default /etc/default/grub file

Context:
I arrived here while investigating a hibernate/resume issue with Ubuntu 15.04 on a Acer C710 (parrot) Chromebook.

Although it is possible to make hibernate/resume functional on this
device, the hibernate action seems to cause recordfail to be set. As a
consequence, I see the grub menu & 30 second countdown on resume. (It's
true that prior to this fix I saw the grub menu with no countdown, which
was even more perplexing - so thank you :)

There were no settings in /etc/default/grub that had a value of 30, so it wasn't immediately obvious to me what was happening.
 
Implementing one of these proposals may avert support questions from laptop users, who experience what might seem an unconfigured / unrequested 30 second delay by grub to laptop resume. OTOH: maybe this configuration is such an edge case it is preferable to do nothing at all

In case someone else arrives here on the same journey, I'll link

issues.
