This is quite useful on laptops such as the Lenovo Yoga, where the power
button is placed on the front side of the laptop and can be pressed by
accident even if the lid is closed.
This reworks a bit of the logind logic to repeatedly try to suspend the
system as long as a lid is closed. We use the new "post" event source
for this, so that we don't keep things busy.
This also adds some code to check the lid status on boot, so that a
powered-off machine that is accidentaly powered on goes into suspend
immediately.
Yay! From now on I can put my Yoga safely in my backpack without fearing
that it might turn itself on and drain the battery.
This new event source is triggered by the dispatching of any non-post
event source. It can thus be used to do clean-up or recheck work,
triggered by any other event source having been executed.
This is different from "defer" event source which are unconditionally
triggered as long as they are enabled. A "defer" event source that does
nothing will result in the event loop busy looping unless it is turned
off eventually. This is different for "post" event sources that will be
only triggered when some other non-post ran, and will thus not keep the
event loop busy on its own.
It doesn't make any sense to symlink this unit file into /etc when the
unit file itself isn't even installed, with --disable-networkd. This
moves the GENERAL_ALIASES logic into the right "if" block.
Prior to 3.2, /proc/sys/kernel/hostname isn't a pollable file and
sd_event_add_io will return EPERM. Ignore this failure, since it isn't
critical to journald operation.
Reported and tested by user sraue on IRC.
Apparently bash doesn't turn off non-blocking mode on stdin/stdout when
reading from it, so be nice to bash. Ideally bash would do this on its
own for robustness reasons, though.

With --rootprefix= systemd-udevd gets installed to /lib/systemd, and since
the network configuration is also required during early boot, it should be
available there with it. Using --prefix= is not an option since it would
put everything, including pkg-config files, man pages, documentation, to /
which is not wanted. This commit puts 99-default.link to
/lib/systemd/network/ when required.
There was a copy-paste error introduced in commit c2ba3ad660
which causes the following error when using timer units:
Assertion '(x->type == SOURCE_MONOTONIC && y->type == SOURCE_MONOTONIC) || (x->type == SOURCE_REALTIME && y->type == SOURCE_REALTIME)'
failed at src/libsystemd/sd-event/sd-event.c:264, function latest_time_prioq_compare(). Aborting.
get_next_elapse() will always fill 'next' with values when it
returns >= 0. Hence, the compiler is wrong about this warning.
Initialize 'next' nevertheless.

This permit to switch to a specific apparmor profile when starting a daemon. This
will result in a non operation if apparmor is disabled.
It also add a new build requirement on libapparmor for using this feature.
Currently on at least Fedora, SELinux policy does not come in the
initramfs. systemd will attempt to load *both* in the initramfs and
in the real root.
Now, the selinux_init_load_policy() API has a regular error return
value, as well as an "enforcing" boolean. To determine enforcing
state, it looks for /etc/selinux/config as well as the presence of
"enforcing=" on the kernel command line.
Ordinarily, neither of those exist in the initramfs, so it will return
"unknown" for enforcing, and systemd will simply ignore the failure to
load policy.
Debian Stable is still using glibc 2.13, which doesn't provide the setns().
So we detect this and provide a tiny wrapper that issues the setns syscall
towards the kernel.
