[ 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.

Title:
systemd should sync disks, before killing all processes on shutdown
Status in systemd package in Ubuntu:
Fix Released
Status in systemd source package in Xenial:
Fix Released
Bug description:
[Impact]
* systemd-shutdown binary is executed to complete system shutdown. In
xenial, it calls sync() after killing all processes, and not before
killing them. This means that processes are racing the SIGKILL/TERM
timeouts to sync all IO to disk. To mitigate this race condition, and
make the shutdown process more reliable the sync() should also happen
before process killing spree starts.
[Fix]
Backport upstream commit
https://github.com/systemd/systemd/commit/2e79d1828a8da9b3af1b052297e3617905ec94f3
[Test Case]
* Make sure systems still shuts down, including e.g. root on raid.
[Regression Potential]
* Shutdowns may appear to be slower due to two sync() calls instead of one
* However total shutdown time should not be impacted much, as there really
should not be much additional IO caused by killing all processes.
