It's not a good idea to create subvolumes for parts of the OS tree (such
as /home, or /var) if the root directory is not a subvolume too. We
shouldn't assume control of "heavier" objects such as subvolumes, if the
originating object (the root directory) is a "light-weight" object, i.e.
a plain directory.

Effectively this means that chroot() environments that are run on a
plain directory do not have to deal with problems around systemd
creating subvolumes that cannot be removed with a simple "rm" anymore.
However, if the chroot manager creates a proper subvolume for such an
environment it will also get further subvolumes placed in there, under
the assumption that the manager understands the concept of subvolumes in
that case.

forwarding controls (unlike as it does for IPv4), but only supports a
global option (#1597). Also, the current per-interface management of the

more interface than the one you configure it on. This created much grief
(#1411, #1808).

Hence, let's roll this logic back and simplify this again, so that we
can expose the same behaviour on IPv4 and IPv6 and things start to work
automatically again for most folks: if a network with this setting set
is set up we propagate the setting into the global setting, but this is
strictly one-way: we never reset it again, and we do nothing for network
interfaces where this setting is not enabled.

Previously, the CCW bus and, in particular, any FCP devices on it, have
been treated separately.  This commit integrates the CCW bus into the
device chain loop.  FCP devices and their associated SCSI disks are now
handled through the common SCSI handling functions in path_id.

This implies also a change in the naming of the symbolic links created
by udev.  So any backports of this commit to existing Linux distribution
must be done with care.  If a backport is required, a udev rule must be
created to also create the "old-style" symbolic links.

Apart from the CCW bus, this commit adds bus support for the:

- ccwgroup bus which manages network devices, and
- ap bus which manages cryptographic adapters
- iucv bus which manages IUCV devices on z/VM

http://lists.freedesktop.org/archives/systemd-devel/2015-November/034880.html

This removes the two XyzOverridable= unit dependencies, that were
basically never used, and do not enhance user experience in any way.
Most folks looking for the functionality this provides probably opt for

core: simplify handling of %u, %U, %s and %h unit file specifiers

Previously, the %u, %U, %s and %h specifiers would resolve to the user
name, numeric user ID, shell and home directory of the user configured
in the User= setting of a unit file, or the user of the manager instance
if no User= setting was configured. That at least was the theory. In
real-life this was not ever actually useful:

- For the systemd --user instance it made no sense to ever set User=,
  since the instance runs in user context after all, and hence the
  privileges to change user IDs don't even exist. The four specifiers
  were actually not useful at all in this case.

- For the systemd --system instance we did not allow any resolving that
  would require NSS. Hence, %s and %h were not supported, unless
  User=root was set, in which case they would be hardcoded to /bin/sh
  and /root, to avoid NSS. Then, %u would actually resolve to whatever
  was set with User=, but %U would only resolve to the numeric UID of
  that setting if the User= was specified in numeric form, or happened
  to be root (in which case 0 was hardcoded as mapping). Two of the
  specifiers are entirely useless in this case, one is realistically
  also useless, and one is pretty pointless.

- Resolving of these settings would only happen if User= was actually
  set *before* the specifiers where resolved. This behaviour was
  undocumented and is really ugly, as specifiers should actually be
  considered something that applies to the whole file equally,
  independently of order...

With this change, %u, %U, %s and %h are drastically simplified: they now
always refer to the user that is running the service instance, and the
user configured in the unit file is irrelevant. For the system instance
of systemd this means they always resolve to "root", "0", "/bin/sh" and
"/root", thus avoiding NSS. For the user instance, to the data for the
specific user.

The new behaviour is identical to the old behaviour in all --user cases
and for all units that have no User= set (or set to "0" or "root").
