be3270ebd3 unit: remove [Install] section from the user exit.target unit
There's no concept of ctrl-alt-del for user systemd instances, hence
don't suggest it woud make sense to symlink the unit to it.

Fixes #1525.

d35c1bb1f4 rfkill: rework and make it listen on /dev/rfkill
With this rework we introduce systemd-rfkill.service as singleton that
is activated via systemd-rfkill.socket that listens on /dev/rfkill. That
way, we get notified each time a new rfkill device shows up or changes
state, in which case we restore and save its current setting to disk.

This is nicer than the previous logic, as this means we save/restore
state even of rfkill devices that are around only intermittently, and
save/restore the state even if the system is shutdown abruptly instead
of cleanly.

This implements what I suggested in #1019 and obsoletes it.

4a9b1dd4ad machine-id-commit: merge machine-id-commit functionality into machine-id-setup
And remove machine-id-commit as separate binary.

There's really no point in keeping this separate, as the sources are
pretty much identical, and have pretty identical interfaces. Let's unify
this in one binary.

Given that machine-id-commit was a private binary of systemd (shipped in
/usr/lib/) removing the tool is not an API break.

While we are at it, improve the documentation of the command substantially.

c2fc2c2560 units: increase watchdog timeout to 3min for all our services

287419c119 containers: systemd exits with non-zero code
When a systemd service running in a container exits with a non-zero
code, it can be useful to terminate the container immediately and get
the exit code back to the host, when systemd-nspawn returns. This was
not possible to do. This patch adds the following to make it possible:

- Add a read-only "ExitCode" property on PID 1's "Manager" bus object.
  By default, it is 0 so the behaviour stays the same as previously.
- Add a method "SetExitCode" on the same object. The method fails when
  called on baremetal: it is only allowed in containers or in user
  session.
- Add support in systemctl to call "systemctl exit 42". It reuses the
  existing code for user session.
- Add exit.target and systemd-exit.service to the system instance.
- Change main() to actually call systemd-shutdown to exit() with the
  correct value.
- Add verb 'exit' in systemd-shutdown with parameter --exit-code
- Update systemctl manpage.

I used the following to test it:

| $ sudo rkt --debug --insecure-skip-verify run \
|            --mds-register=false --local docker://busybox \
|            --exec=/bin/chroot -- /proc/1/root \
|            systemctl --force exit 42
| ...
| Container rkt-895a0cba-5c66-4fa5-831c-e3f8ddc5810d failed with error code 42.
| $ echo $?
| 42

ed15589c98 bus-proxy: increase NOFILE limit
The bus-proxy manages the kdbus connections of all users on the system
(regarding the system bus), hence, it needs an elevated NOFILE.
Otherwise, a single user can trigger ENFILE by opening NOFILE connections
to the bus-proxy.

Note that the bus-proxy still does per-user accounting, indirectly via
the proxy/fake API of kdbus. Hence, the effective per-user limit is not
raised by this. However, we now prevent one user from consuming the whole
FD limit of the shared proxy.

Also note that there is no *perfect* way to set this. The proxy is a
shared object, so it needs a larger NOFILE limit than the highest limit
of all users. This limit can be changed dynamically, though. Hence, we
cannot protect against it. However, a raised NOFILE limit is a privilege,
so we just treat it as such and basically allow these privileged users to
be able to consume more resources than normal users (and, maybe, cause
some limits to be exceeded by this).

Right now, kdbus hard-codes 1024 max connections per user on each bus.
However, we *must not* rely on this. This limits could be easily dropped
entirely, as the NOFILE limit is a suitable limit on its on.

d537694a98 terminal: drop unfinished code
This drops the libsystemd-terminal and systemd-consoled code for various
reasons:

 * It's been sitting there unfinished for over a year now and won't get
   finished any time soon.

 * Since its initial creation, several parts need significant rework: The
   input handling should be replaced with the now commonly used libinput,
   the drm accessors should coordinate the handling of mode-object
   hotplugging (including split connectors) with other DRM users, and the
   internal library users should be converted to sd-device and friends.

 * There is still significant kernel work required before sd-console is
   really useful. This includes, but is not limited to, simpledrm and
   drmlog.

 * The authority daemon is needed before all this code can be used for
   real. And this will definitely take a lot more time to get done as
   no-one else is currently working on this, but me.

 * kdbus maintenance has taken up way more time than I thought and it has
   much higher priority. I don't see me spending much time on the
   terminal code in the near future.

If anyone intends to hack on this, please feel free to contact me. I'll
gladly help you out with any issues. Once kdbus and authorityd are
finished (whenever that will be..) I'll definitely pick this up again. But
until then, lets reduce compile times and maintenance efforts on this code
and drop it for now.

1b09f548c7 turn kdbus support into a runtime option
./configure --enable/disable-kdbus can be used to set the default
behavior regarding kdbus.

If no kdbus kernel support is available, dbus-dameon will be used.

With --enable-kdbus, the kernel command line option "kdbus=0" can
be used to disable kdbus.

With --disable-kdbus, the kernel command line option "kdbus=1" is
required to enable kdbus support.

96d9117ad2 fsck: remove fsckd again, but keep the door open for external replacement
For a longer discussion see this:

http://lists.freedesktop.org/archives/systemd-devel/2015-April/030175.html

This introduces /run/systemd/fsck.progress as a simply
AF_UNIX/SOCK_STREAM socket. If it exists and is connectable we'll
connect fsck's -c switch with it. If external programs want to get
progress data they should hence listen on this socket and will get
all they need via that socket. To get information about the connecting
fsck client they should use SO_PEERCRED.

Unless /run/systemd/fsck.progress is around and connectable this change
reverts back to v219 behaviour where we'd forward fsck output to
/dev/console on our own.

We support /var, /tmp and /var/tmp on NFS. NFS shares however are by
default ordered only before remote-fs.target which is a late-boot

explicitly order them before basic.target.

Note that this change simply makes explicit what was implicit before,
since many early-boot services pulled in parts of /var anyway early.

113b3fc1a8 importd: create a loopback btrfs file system for /var/lib/machines, if necessary
When manipulating container and VM images we need efficient and atomic
directory snapshots and file copies, as well as disk quota. btrfs
provides this, legacy file systems do not. Hence, implicitly create a
loopback file system in /var/lib/machines.raw and mount it to
/var/lib/machines, if that directory is not on btrfs anyway.

This is done implicitly and transparently the first time the user
invokes "machinectl import-xyz".

This allows us to take benefit of btrfs features for container
management without actually having the rest of the system use btrfs.

The loopback is sized 500M initially. Patches to grow it dynamically are
to follow.
