systemd (229-4ubuntu21.2) xenial; urgency=medium

  [ Dimitri John Ledkov ]
  * udev: Mark ndb devices as inactive until connected. (LP: #696435)
  * networkd: in dhcp, change UseMTU default to true, to accept DHCP provided 
MTU by default.
(LP: #1717471)
  * sysctl: apply parameters in-order, instead of randomly. (LP: #1718444)
  * networkd: apply promote_secondaries, to make DHCP lease changes work.
(LP: #1721223)
  * shutdown: sync filesystems, before going into a killing spree.
(LP: #1722481)
  * sysctl: do not fail, when cannot apply sysctl changes due to read-only 
sysfs in containers.
(LP: #1734409)
  * networkd,wait-online: add RequiredForOnline to mark mandatory/optional 
links for boot.

   * Original bug report.

  systemd-sysctl in Xenial forces itself over procps by shipping a link
  for procps.service to systemd-sysctl.service. However, it does not
  obey the order both of the files and also of the sysctls within the
  files. Instead it uses a simple hashmap. As it turns out that's fixed
  upstream and systemd master uses an ordered hashmap because of this,
  which at least preserves order within single files. Traditionally
  files in sysctl.d have been prefixed with numbers to ensure an order
  and that's now completely non-deterministic on Xenial.

  Relevant upstream commit:
  
https://github.com/systemd/systemd/commit/886cf982d3018f7451f0548dadbc05bd2d583bb6

  Note that conf_files_list_nulstr in master sorts the configuration
  files using strcmp, so even order of configuration files should be
  obeyed.

[Touch-packages] [Bug 1718444] Re: systemd-sysctl in Xenial is not obeying the order of the sysctls

[Dimitri John Ledkov]

Use multipass to launch a xenial VM with

$ dpkg-query -W systemd
systemd 229-4ubuntu21.1

Execute
SYSTEMD_DEBUG_LEVEL=debug /lib/systemd/systemd-sysctl

A few times, to notice that the output is "jumpy" and the order of the
error messages is unstable. Realising that the sorting / application of
the sysctls is not performed in a stable order.

Upgraded to

$ dpkg-query -W systemd
systemd 229-4ubuntu21.2

Rerunning the above command again, and again, and again, shows
unchanging output on the terminal, meaning the order of all the things
that were attempted to be written is now stable.

[Brian Murray]

Hello Philipp, or anyone else affected,

Accepted systemd into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/229-4ubuntu21.2 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 on 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-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, without details of
your testing we will not be able to proceed.

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