faa368e337 conf-parser: don't unescape parsed configuration strings by default
In many cases this might have a negative effect since we drop escaping
from strings where we better shouldn't have dropped it.

If unescaping makes sense for some settings we can readd it later again,
on a per-case basis.

a866073d35 main: when transitioning from initrd to the main system log to kmsg
When the new PID is invoked the journal socket from the initrd might
still be around. Due to the default log target being journal we'd log to
that initially when the new main systemd initializes even if the kernel
command line included a directive to redirect systemd's logging
elsewhere.

With this fix we initially always log to kmsg now, if we are PID1, and
only after parsing the kernel cmdline try to open the journal if that's
desired.

(The effective benefit of this is that SELinux performance data is now
logged again to kmsg like it used to be.)

72edcff5db hwclock: always set the kernel's timezone
Properly tell the kernel at bootup, and any later time zone changes,
the actual system time zone.

Things like the kernel's FAT filesystem driver needs the actual time
zone to calculate the proper local time to use for the on-disk time
stamps.

4096d6f587 main: bump up RLIMIT_NOFILE for systemd itself
For setups with many listening sockets the default kernel resource limit
of 1024 fds is not enough. Bump this up to 64K to avoid any limitations
in this regard. We are careful to pass on the kernel default to daemons
however, since normally resource limits are a good to enforce,
especially since select() can't handle fds > 1023.

0bb91b5010 udev: add btrfs support
All "btrfs" file systems will be registered with the kernel when they
show up.

Incomplete multi-device volumes will set SYSTEMD_READY=0, to prevent
access until the volume is complete and fully registered.

d9cfd69403 man: generate an index of directives
Systemd has a large (and growing) number of manpages. Sometimes it's
not immediately obvious, where to look for a directive. Especially,
when something is described in more than one place. Making sense of
all the settings should be easier with an index.

98a77df5fe logind: make sure there's always a getty available on TTY6
Previously, if X allocated all 6 TTYs (for multi-session for example) no
getty would be available anymore to guarantee console-based logins.

With the new ReserveVT= switch in logind.conf we can now choose one VT
(6 by default) that will always be subject to autovt-style activation,
i.e. we'll always have a getty on TTY6, and X will never take possession
of it.

54693d9bfa tmpfiles: use write(2) for the 'w' action
This resolves problems with filesystems which do not implement the
aio_write file operation. In this case, the kernel will fall back using
a loop writing technique for each pointer in a received iovec. The
result is strange errors in dmesg such as:

[   31.855871] elevator: type  not found
[   31.856262] elevator: switch to
[   31.856262]  failed

It does not make sense to implement a synchronous aio_write method for
sysfs as this isn't a real filesystem where a reasonable use case for
using writev exists, nor is there an expectation that tmpfiles will be
used to write more data than can be reasonably written in a single write
syscall.

In addition, some sysfs attrs are currently buggy and will NOT reject
the second write with the newline, causing the sysfs value to be zeroed
out. This of course should be fixed in the kernel regardless of any
wrongdoing in userspace, but this simple change makes us immune to such
a bug.

This change means that we do not write a trailing newline by default, as
the expected use case of 'w' is for sysfs and procfs. In exchange, honor
C-style backslash escapes so that if the newline is really needed, the
user can add it.

ede89845a4 nspawn: mount tmpfs on /dev/shm
Most things seem to function fine without /dev/shm, but it is expected
to be there (quoting linux/Documentation/filesystems/tmpfs.txt:
glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for POSIX
shared memory (shm_open, shm_unlink)).

Since /tmp/ is already mounted as tmpfs, it would be enough to mkdir
/tmp/shm and chmod it. Mounting it separately has the advantage that
it can be easily remounted to change the quota.

4a271908f1 logind: redefine idleness to start at last activity
Before, after the timeout, a session would be timestamped as idle
since 'last activity' + 'idle timeout'. Now, it is timestamped as idle
since 'last activity'.

Before, after all sessions were idle, the seat would be marked with as
idle with the timestamp of the oldest idle session. Now it is
marked with the timestamp of the youngest idle session.

Both changes seem to me to be closer to natural understanding of
idleness: the time since last activity counts.

92c4ef2d35 timedated: gather timezone from /etc/localtime sym target
/etc/localtime -> /usr/share/zoneinfo/...

or

/etc/localtime -> ../usr/share/zoneinfo/...

(note, ../usr is not the same if /etc is a symlink, as this isn't
using canonicalize_file_name())

keep other method for now, consider dropping later.

Supporting relative links here are problematic as timezones in
/usr/share/zoneinfo are often themselves symlinks (and symlinks to
symlinks), so this implamentation only supports absolute symlinks
"/usr/share/zoneinfo/" and relative symlinks starting with
"../usr/share/zoneinfo/"

>From TODO (kay sievers):
* kill /etc/timezone handling entirely? What does it provide?
  - /etc/localtime carries the same information already:
      $ ls -l /etc/localtime; cat /etc/timezone
      lrwxrwxrwx 1 root root 33 Jul 27 09:55 /etc/localtime -> /usr/share/zoneinfo/Europe/Berlin
      Europe/Berlin
  - systemd enforces /usr to be available at bootup, so we can
    enforce the use of the symlink

cdefbd6aeb build-sys: Append -Werror when testing flags
Clang don't treat unknown warnings flags as an error, but rather as a
warning. The result is that the detection for whic CFLAGS are supported
by this compiler will not work, since the compilation will succeed.

With this patch we now successfully detect clang doesn't support
-Wlogical-op, as opposed to previous behavior:

	checking if clang supports flag -Wlogical-op in envvar CFLAGS... no

We use this macro only for LDFLAGS and CFLAGS, so it's safe to stash
-Werror there.

095b2d7ab9 load-fragment: Expand specifiers in conditions.
Add specifier expansion to Path and String conditions.

Specifier expansion for conditions will help create instance
and user session units by allowing us to template conditions
based on the instance or user session parameters.

An example would be a system-wide user session service file
that conditionally runs based on whether a user has the
service configured through a configuration file in ~/.config/.
