[Andy Whitcroft]

Hello seahawk1986, or anyone else affected,

Accepted systemd into yakkety-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/systemd/231-9ubuntu1 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
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
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  Regression: systemd does not send all queued DBus Signals when a unit
  gets inactive

Bug description:
  Since the penultimate systemd package update in september
  (229-4ubuntu8) systemd does not send the remaining queued DBus signals
  (e.g. PropertiesChanged) when a unit's state changes to inactive.

  Sending those signals has been working since the release of Ubuntu
  16.04 and it is quite unfortunate for my use case this got broken
  while fixing another bug.

  Adding this upstream change to the package restores the old
  functionality (a patch for the current systemd package (systemd
  229-4ubuntu10) for xenial is attached):
  https://github.com/systemd/systemd/commit/0dd99f86addd1f81e24e89807b6bc4aab57d5793

  SRU TEST CASE: See comment #8
  Regression potential: Low; the patch only widens the condition when a change signal is sent, thus at most clients would now get more D-Bus signals than before (in particular, the missing one at becoming inactive).
