hours, and then in the -proposed repository.

Please help us by testing this new package.  See

mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help

  plymouth loses output to /dev/console (such as ci-info: messages)

Bug description:
  During early boot, plymouth captures writes to /dev/console.  As I
  understand it, it is supposed to re-play that content later.  Whether
  or not it intends to is not the issue.  In our cloud-images (and in
  other cases) users may write data to /dev/console that needs to be
  seen on the other side (ie a serial logger or 'get-console-ouptput'
  api call).

  See the attached 'my-logger.conf' for an upstart job that simply
  writes data early in boot to /dev/console.  Sometimes data "lost" is
  available in /var/log/boot.log, but sometimes it doesn't even seem to
  make it there.  bug 682831 has an attachment 'myhack-init' that does a
  similar thing but starts outputting by replacing /sbin/init and then
  calling /sbin/init itself.

  == Original bug report ==
  On precise cloud images, I get a console output line like this:

  ci-info: eth0  : 1 192.168.122.204 255.255.255.0   52:54:00:7f:d8:ca^M

  On saucy cloud images, this is missing.
