Otherwise we might end up in an endless stop loop.

Fixes a regression introduced in be7d9ff730cb88d7c6a869dd5c47754c78ceaef2.

gone from *all* lines
Devices might be referenced by multiple mount points in
/proc/self/mountinfo, hence we should consider them unmounted only after
they disappeared from all lines, not just from one.

Change device_found_node() to also create a .device unit if a device is not
known by udev; this is the case for "tentative" devices picked up by mountinfo
(DEVICE_FOUND_MOUNT). With that we can record the "found" attribute on the
unit.
Change device_setup_unit() to also accept a NULL udev_device, and don't
add the extra udev information in that case.
Previously device_found_node() would not create a .device unit, and
unit_add_node_link() would then create a "dead" stub one via
manager_load_unit(), so we lost the "found" attribute and unmounted everything
from that device.

The hostname(1) tool allows comments in /etc/hostname. Introduce a new
read_hostname_config() in hostname-util which reads a hostname configuration
file like /etc/hostname, strips out comments, whitespace, and cleans the
hostname. Use it in hostname-setup.c and hostnamed and remove duplicated code.
Update hostname manpage. Add tests.

This allows us to ensure that Requisite= dependencies never cause
propagation between units, while Requires= dependencies might.

Instead of use LIST_FOREACH_SAFE, just use the same, seperate destructor
everywhere.
|
|
All functions should either log the errors they run into, or only return
them in which case the caller should log them.
Make sure this rule is followed, so that each error is logged precisely
once, and neither never, nor more than once.

So far we tried to reserve the _t suffix to types we use like a value in
contrast to types we use as objects, hence let's do this in journalctl
too.

|
|
let's try to be valgrind clean
|
|
That way we can be sure we execute the destructors properly, and can be
valgrind-clean.

This method should greatly improve offset based lookup, by simply jumping
from one boot to the next boot. It starts at the journal head to get the
a boot ID, makes a _BOOT_ID match and then comes from the opposite
journal direction (tail) to get to the end that boot. After flushing the matches
and advancing the journal from that exact position, we arrive at the start
of next boot. Rinse and repeat.
This is faster than the old method of aggregating the full boot listing just
so we can jump to a specific boot, which can be a real pain on big journals
just for a mere "-b -1" case.
As an additional benefit --list-boots should improve slightly too, because
it does less seeking.
Note that there can be a change in boot order with this lookup method
because it will use the order of boots in the journal, not the realtime stamp
stored in them. That's arguably better, though.
Another deficiency is that it will get confused with boots interleaving in the
journal, therefore, it will refuse operation in --merge, --file and --directory mode.

Makes it a bit clearer what is going on, rather than jumping to the end of main().

This uses kill_and_sigcont() instead of kill(), otherwise no functional change.

We were returning rather than continuing in some cases. The intention
was always to fully process all pending events before returning
from the SIGCHLD handler. Restore this behaviour.

They might be created as result of merged answer sets, hence accept

When systemd-nspawn gets exec*()ed, it inherits the followings file
descriptors:
- 0, 1, 2: stdin, stdout, stderr
- SD_LISTEN_FDS_START, ... SD_LISTEN_FDS_START+LISTEN_FDS: file
descriptors passed by the system manager (useful for socket
activation). They are passed to the child process (process leader).
- extra lock fd: rkt passes a locked directory as an extra fd, so the
directory remains locked as long as the container is alive.
systemd-nspawn used to close all open fds except 0, 1, 2 and the
SD_LISTEN_FDS_START..SD_LISTEN_FDS_START+LISTEN_FDS. This patch delays
the close just before the exec so the nspawn process (parent) keeps the
extra fds open.
This patch supersedes the previous attempt ("cloexec extraneous fds"):

When a service is chrooted with the option RootDirectory=/opt/..., then
the options PrivateDevices, PrivateTmp, ProtectHome, ProtectSystem must
mount the directories under $RootDirectory/{dev,tmp,home,usr,boot}.
The test-ns tool can test setup_namespace() with and without chroot:
$ sudo TEST_NS_PROJECTS=/home/lennart/projects ./test-ns
$ sudo TEST_NS_CHROOT=/home/alban/debian-tree TEST_NS_PROJECTS=/home/alban/debian-tree/home/alban/Documents ./test-ns

Load kdbus.ko only if we are built with kdbus, and load ip_tables.ko
only if we are built with iptables support.

Currently we have no way how to specify dependencies between fstab
entries (or another units) in the /etc/fstab. It means that users are
forced to bypass fstab and write .mount units manually.
The patch introduces new systemd fstab options:
x-systemd.requires=<PATH>
- to specify dependence an another mount (PATH is translated to unit name)
x-systemd.requires=<UNIT>
- to specify dependence on arbitrary UNIT
x-systemd.requires-mounts-for=<PATH ...>
- to specify dependence on another paths, implemented by
RequiresMountsFor=. The option may be specified more than once.
For example two bind mounts where B depends on A:
/mnt/test/A /mnt/test/A none bind,defaults
/mnt/test/A /mnt/test/B none bind,x-systemd.requires=/mnt/test/A
More complex example with overlay FS where one mount point depends on
"low" and "upper" directories:
/dev/sdc1 /mnt/low ext4 defaults
/dev/sdc2 /mnt/high ext4 defaults
overlay /mnt/merged overlay lowerdir=/mnt/low,upperdir=/mnt/high/data,workdir=/mnt/high/work,x-systemd.requires-mounts-for=/mnt/low,x-systemd.requires-mounts-for=mnt/high

reenable and disable.
compadd's -a option treats non-option arguments as arrays. So
$(_systemctl_get_template_names) expands to some words that aren't
legal array names. Even if there were, they would be empty; thus adding
nothing.
deduplicated a few functions too.

--irreversible/--ignore-dependencies/--fail are deprececated since 4dc5b821ae737914499119e29811fc3346e3d97c.
Also add shell completions for --jobs-mode.
