3907446f02 link-config: add "keep" policy and use it by default
If "keep" policy is specified, and the interface has a name that is
NET_NAME_USER or NET_NAME_RENAMED, we stop processing rules. "keep" should
probably be specified either first or last depending on the preference.

This partially reimplements 55b6530baa, in the
sense that if the "keep" policy is not specified, and if the interface has
a NamingPolicy, it will be renamed, even if it had a name previously.
So this breaks backwards compatibility in this case, but that's more in line
with what users expect.

Closes #9006.

Based on the journalctl documentation of this option added in 23ad99b519

04ca4d191b Improve kernel-install support for initrd files. (#11281)
The current support in kernel-install for initrd images doesn't copy
over the initrd file or allow a means for it to be specified (it
requires a specific filename in a particular directory).

This patchset adds support for (optionally) providing the name of
initial ramdisk file to copied over and used by kernel-install.

3f9a0a522f tree-wide: s/time-out/timeout/g
From WordNet (r) 3.0 (2006) [wn]:

  time-out
      n 1: a brief suspension of play; "each team has two time-outs left"

From The Free On-line Dictionary of Computing (18 March 2015) [foldoc]:

  timeout

     A period of time after which an error condition is raised if
     some event has not occured.  A common example is sending a
     message.  If the receiver does not acknowledge the message
     within some preset timeout period, a transmission error is
     assumed to have occured.

06da5c63dd meson: make net.naming-scheme= default configurable
This is useful for distributions, where the stability of interface names should
be preseved after an upgrade of systemd. So when some specific release of the
distro is made available, systemd defaults to the latest & greatest naming
scheme, and subsequent updates set the same default. This default may still
be overriden through the kernel and env var options.

A special value "latest" is also allowed. Without a specific name, it is harder
to verride from meson. In case of 'combo' options, meson reads the default
during the initial configuration, and "remembers" this choice. When systemd is
updated, old build/ directories could keep the old default, which would be
annoying. Hence, "latest" is introduced to make it explicit, yet follow the
upstream. This is actually useful for the user too, because it may be used
as an override, without having to actually specify a version.

f7e81fd96f udev: introduce udev net_id "naming schemes"
With this we can stabilize how naming works for network interfaces. A
user can request through a kernel cmdline option or an env var which
scheme to follow. The idea is that installers use this to set into stone
(a very soft stone though) the scheme used during installation so that
interface naming doesn't change afterwards anymore.

Why use env vars and kernel cmdline options, and not a config file of
its own?

Well, first of all there's no obvious existing one to use. But more
importantly: I have the feeling that this logic is kind of an incomplete
hack, and I simply don't want to do advertise this as a perfectly
working solution. So far we used env vars for the non-so-official
options and proper config files for the official stuff. Given how
incomplete this logic is (i.e. the big variable for naming remains the
kernel, which might expose sysfs attributes in newer versions that we
check for and didn't exist in older versions — and other problems like
this), I am simply not confident in giving this first-class exposure in
a primary configuration file.

abcb67ceed man: rewrite the general description of tmpfiles
We would describe tmpfiles.d through what systemd-tmpfiles does with them, but
I think it's better to start with a geneneral statement what they are. Also,
let's make the description of volatile file systems less prominent.

Also, strenghten the advice to use RuntimeDirectory and mention
{Cache,Logs,Configuration,State}Directory=.

488e435253 man: reword tmpfiles.d descriptions to refer less to previous descriptions
I think it is OK if some option is described as "similar to ..., but in
addition ...", as long as the "in addition" part is strictly additive this is
unambiguous. Otherwise, we'd have to repeat a lot of text, and then we'd
probably forget to adjust some of the descriptions when doing changes.

But when the "in addition" part is about replacing or removing parts of
functionality, it is better to avoid this pattern and describe the later option
from scratch.

Some paragraph breaks are added and minor changes made. UID/GID is changed to
user/group, since we generally expect user/group names to be used, not numeric
ids.

b6854081ff udevadm: allow a .device unit to be specified for query and trigger
This is convenient when working with device units in systemd. Instead of
converting the systemd unit name to a path to feed to udevadm, udevadm
info|trigger can be called directly on the unit name.

The man page is reworked a bit to describe the modern syntax with positional
arguments first. It's just simpler to use than the positional options.

c90ee83400 coding style: reduce text width to 109 characters
Patches are shown on github with a fixed width (no matter how wide the window
is). When line numbers are high (we have some files with 5 digit line numbers),
the diff does not fit, and horizontal scrolling must be used when viewing the
patch. This is super annoying. Let's reduce the width a bit. I think 109 is
still very wide, but at least the github issue should be alleviated.

c72703e26d cgroup: Add DisableControllers= directive to disable controller in subtree
Some controllers (like the CPU controller) have a performance cost that
is non-trivial on certain workloads. While this can be mitigated and
improved to an extent, there will for some controllers always be some
overheads associated with the benefits gained from the controller.
Inside Facebook, the fix applied has been to disable the CPU controller
forcibly with `cgroup_disable=cpu` on the kernel command line.

This presents a problem: to disable or reenable the controller, a reboot
is required, but this is quite cumbersome and slow to do for many
thousands of machines, especially machines where disabling/enabling a
stateful service on a machine is a matter of several minutes.

Currently systemd provides some configuration knobs for these in the
form of `[Default]CPUAccounting`, `[Default]MemoryAccounting`, and the
like. The limitation of these is that Default*Accounting is overrideable
by individual services, of which any one could decide to reenable a
controller within the hierarchy at any point just by using a controller
feature implicitly (eg. `CPUWeight`), even if the use of that CPU
feature could just be opportunistic. Since many services are provided by
the distribution, or by upstream teams at a particular organisation,
it's not a sustainable solution to simply try to find and remove
offending directives from these units.

This commit presents a more direct solution -- a DisableControllers=
directive that forcibly disallows a controller from being enabled within
a subtree.
