[Bug 1096531] Re: After touch /forcefsck and reboot: Assertion failed in log_clear_unflushed

[James Hunt]

Work-arounds for this problem:

= Work-Around 1 =

Boot with '--no-log' on kernel command-line.

EFFECT: This will disable all job log output. This is potentially rather
extreme, so users may wish to use work-around 2 below.

= Work-Around 2 =

1) Boot with '--no-log' on kernel command-line.

2) Disable the flush-early-job-log job:

    echo manual | sudo tee /etc/init/flush-early-job-log job.override

3) Reboot.

EFFECT: This will throw away data that jobs produce before the disk
becomes writeable, which tends to be minimal since only a very few jobs
start this early in the boot process.

File /etc/init/flush-early-job-log job.override should be deleted once a
fix for this bug is available in Ubuntu.

Bug description:
  I made a copy of raring-server-cloudimg-amd64-disk1.img, launched in
  KVM on my 12.10 system, updated all the packages on it and then
  rebooted it after touching /forcefsck.  Even though its a clean
  reboot, it still core dumpes.
