* Order systemd-user-sessions.service after nss-user-lookup.target. We
  should not allow logins before NIS/LDAP users are available.
* Order systemd-user-sessions.service after network.target. That way we can
  be sure that local users are logged out and SSH sessions are ended cleanly
  before the network is shut down when the system goes down.

Use ConditionPathExists=/dev/tty0, the same check as in getty@.service,
to determine whether we have a functional VC subsystem and we should
start any gettys.

Closes: #824779

Avoids repeated unsuccessful start attempts of agetty inside (docker)
containers.

Closes: #829537

The systemd.resource-control man page had references to /cgroups/ which
moved to /cgroup-v1/.

Closes: #819970

Otherwise a disabled event source can get swapped with an enabled one
and cause a severe sd-event malfunction, breaking the event loop.

Closes: #828006

This ensures that services are properly killed after a given timeout.

Closes: #813702

Do not fail when modifying an existing link.

Closes: #813696

Otherwise we break booting with dracut which uses systemd inside the
initramfs.

Closes: #810748

Don't call addgroup with --quiet, so that if the "input"
group already exists as a non-system group you get a sensible error
message. Some broken tutorials forget the --system option.
Do the same when creating the systemd-journal group.

Closes: #769948
LP: #1455956
Closes: #762275

This avoids that swap devices are being stopped prematurely
during shutdown.

Closes: #805133

Prevents future upgrade failures with versioned Breaks: to udev like

  De-configuring udev (228-2ubuntu1) ...
  /var/lib/dpkg/info/udev.prerm called with unknown argument 'deconfigure'
  dpkg: error processing archive /home/ubuntu/./lvm2_2.02.133-1ubuntu1_amd64.deb (--unpack):
   subprocess installed pre-removal script returned error exit status 1

via RequestBroadcast=. This is a backport from upstream which doesn't
change the default setting.

Closes: #797894

Closes: #793477

Otherwise, every daylight saving time change or time zone change by
travelling will make the time jump, and the local time might jump
backwards which creates unsolvable problems with file timestamps.

Closes: #759319

Closes: #802897

Closes: #787758

Some kernel modules, like mptsas, can take longer then 30s to load so
udevd kills the (hanging) worker responsible for loading the module.
Increase timeout from 30s to 180s to workaround this issue.
Thanks Faidon Liambotis.

Closes: #787191

The .pc files of the compat libraries declare a strictly versioned
dependency on libsystemd.pc, so reflect that in the package dependencies
as well.

Closes: #794290

In v215 they are always added to resolv.conf as fallback entries even
when DNS servers were acquired from systemd-networkd.

Closes: #787731

To make this work with busybox grep.

Thanks Faidon Liambotis!

Closes: #765577

This leads to problems like bash not being able to write its history, mosh not
saving its state, and similar failed cleanup actions.

have_ask_password contains negative error values which have to be
negated when being passed to strerror().

Improve commit bf0b11 to fail on invalid offset= values. It's too dangerous to
ignore in this case. Also fix a changelog typo.

This reverts commit 6b8b9448.

The actual 215-17 upload didn't contain this commit, so revert it for
now.

LP: #953875

Newer versions of initramfs-tools already fsck and mount / and /usr in
the initramfs. Skip the filesystem check in this case.

This makes fstab-generator-don-t-rely-on-usr-being-mounted-in-t.patch
obsolete, so remove it.

Closes: #782522

This should make password prompts without plymouth more usable.
