In some cases, like wrong configuration, restarting after error
does not help, so administrator can specify statuses by RestartPreventExitStatus
which will not cause restart of a service.
Sometimes you have non-standart exit status, so this can be specified
by SuccessfulExitStatus.

- don't use pivot_root() anymore, just reuse root hierarchy
- first create all mounts, then mark them read-only so that we get the
right behaviour when people want writable mounts inside of
read-only mounts
- don't pass invalid combinations of MS_ constants to the kernel

also a number of minor fixups and bug fixes: spelling, oom errors
that didn't print errors, not properly forwarding error codes,
few more consistency issues, et cetera

glibc/glib both use "out of memory" consistantly so maybe we should
consider that instead of this.
Eliminates one string out of a number of binaries. Also fixes extra newline
in udev/scsi_id

./src/shared/util.c:2457:45: warning: 'r' may be used uninitialized in this function [-Wmaybe-uninitialized]

This is to match strappend() and the other string related functions.

initrds can only be on tmpfs or ramfs, so check for that

|
|
This adds a timeout if the TTY cannot be acquired and makes sure we
always output the question to the console, never to the TTY of the
respective service.

src/shared/util.c includes <sys/capability.h> but doesn't use anything
defined there. Since <sys/capability.h> is part of libcap, not libc,
don't require it.
Allows systemd-without-udevd to require fewer external libraries.

This takes handling of chassis power and sleep keys as well as the lid
switch over from acpid.
This logic is enabled by default for power and sleep keys, but not for
the lid switch.
If a graphical session is in the foreground no action is taken under the
assumption that the graphical session does this.

Checking the device major/minor is not a good idea. Let's replace this
with an explicit flag file, which we model after /etc/os-release and
call /etc/initrd-release.

if root_dev is set, remove subdirectories only, if the device is the
same as the root_dev. This prevents to remove files across device
boundaries.
|
|
in_initrd() checks, if the stat() for the device for "/" is 1, which it
is for the initramfs.
|
|
do_switch_root now mount moves "/dev", "/proc", "/sys", "/run" and
removes the old root recursively.

This should help making the boot process a bit easier to explore and
understand for the administrator. The simple idea is that "systemctl
status" now shows a link to documentation alongside the other status and
decriptionary information of a service.
This patch adds the necessary fields to all our shipped units if we have
proper documentation for them.

can't write the trailing newline

The alignment of the "[ OK ]" and "[FAILED]" status marks to the right
side of the terminal makes it difficult to link them with the messages
on the left if your console is wide.
I considered the options:
1. Align them to the 80th column regardless of the console width.
Disadvantage - either:
- truncating messages needlessly, not using available space; or
- If the message is long, write the mark over it. => ugly
2. Write them to the 80th column for short messages,
and further to the right for longer ones.
Disadvantage:
- jagged look
3. Write the marks on the left, before the message.
Disadvantage:
- Breaks tradition from RHL.
Advantages:
+ slightly simpler code
+ Will annoy holy-traditionalists.
I chose option 3.
BTW, Debian now uses similar marks on the left with its makefile-style
boot.
Special values of the "status" argument to status_vprintf are:
NULL - no status mark, no message indentation
"" - no status mark, message indented as if the mark was there

File names in /etc, /run, /usr/lib are sorted/overridden by basename.
Sorting things like "/dev/null" with the basename "null" in the hash
of config files breaks the ordering and the overriding logic.

/sys/class/tty/console/active is misleading

We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.
Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.
The bits that used to be MIT continue to be MIT.
The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.

Leave the env vars used in the container/initrd logic set for PID1, but
don't inherit them to any children.

Only 34 of 74 tools need libselinux linked, and libselinux is a pain
