[Bug 50437] Re: Resume from hibernation may fail because swap partition UUID does not match /etc/initramfs-tools/conf.d/resume

[Andy Whitcroft]

This should have been fixed by the commit below:

  commit fef37d599aae9f2f3fc6808b46e901a7a4267c76
  Author: maximilian attems <maks at debian.org>
  Date:   Wed Sep 11 00:40:10 2013 +0200

    hooks: Add resume hook instead of hardcoding RESUME once on preinst

This was part of debian v0.114 and therefore part of v0.120ubuntu1.

** Changed in: initramfs-tools (Ubuntu)
       Status: Triaged => Fix Released

Title:
  Resume from hibernation may fail because swap partition UUID does not
  match /etc/initramfs-tools/conf.d/resume

Status in initramfs-tools package in Ubuntu:
  Fix Released
Status in ubiquity package in Ubuntu:
  Invalid
Status in Baltix:
  Confirmed

Bug description:
  There are a variety of circumstances which can cause the swap
  partition UUID to get out of sync with the system configuration, for
  example:

  1. User edits /etc/fstab to specify a different swap partition, either by UUID or by hardcoding the device path
  2. User reinitializes their swap partition with a new UUID using mkswap
  3. User repartitions their disk and thereby reinitializes the swap partition with a new UUID

  If this happens, the system will fail to resume from hibernation
  because it continues to look for the swap partition as specified in
  /etc/initramfs-tools/conf.d/resume.  Not finding this device, it will
  continue with normal system startup, as if no hibernation had taken
  place.

  It would be better if the system were more robust in the face of such
  changes.
