And move it to sperate function.

Currently "systemctl set-default" will fail to change the default target
due to the 'default.target' being a symlink which is always the case.
To work around this, the user must specify the "--force" switch to be
able to overwrite the existing symlink.
This is clearly a regression that was introduced by commit 718db96199e
since it worked before without the "--force" switch and the man pages do
not mention that you need to specify it. It is expected that this is a
symlink.
So just explicity set the force flag to make it work again.

greedy_realloc() and greedy_realloc0() now store the allocated
size as the count, not bytes.
Replace GREEDY_REALLOC uses with GREEDY_REALLOC_T everywhere,
and then rename GREEDY_REALLOC_T to GREEDY_REALLOC. It is just
too error-prone to have two slightly different macros which do the
same thing.

GCC optimizes strlen("string constant") to a constant, even with -O0.
Thus, replace patterns like sizeof("string constant")-1 with
strlen("string constant") where possible, for clarity. In particular,
for expressions intended to add up the lengths of components going into
a string, this often makes it clearer that the expression counts the
trailing '\0' exactly once, by putting the +1 for the '\0' at the end of
the expression, rather than hidden in a sizeof in the middle of the
expression.

utmp_wall() now takes an optional argument 'username_override' which
allows the caller to override the username shown on wall messages.
journald will use this to inform users that its wall messages comes from
'systemd-journald'.

overall system state
Previously "systemctl status" without argument would print the status of
all loaded units. This has now been moved to "systemctl status -a".
|
|
"systemctl list-machines" shows one line per local container which
includes the current system state of the container, the number of failed
units as well as the number of currently queued jobs.

If "systemctl switch-root" is called with a specific "INIT" or
/proc/cmdline contains "init=", then systemd would not serialize
itsself.
Let systemctl check, if the new init is in the standard systemd
installation path and if so, clear the INIT parameter,
to let systemd serialize itsself.
|
|
for the unit that is created
The code for parsing these properties is shared with "systemctl
set-property", which means all the resource control settings are
immediately available.
|
|
This mirrors set_consume and makes the common use a bit nicer.
|
|
/run was already used almost everywhere, fix the remaining places
for consistency.

for sizes
According to Wikipedia it is customary to specify hardware metrics and
transfer speeds to the basis 1000 (SI decimal), while software metrics
and physical volatile memory (RAM) sizes to the basis 1024 (IEC binary).
So far we specified everything in IEC, let's fix that and be more
true to what's otherwise customary. Since we don't want to parse "Mi"
instead of "M" we document each time what the context used is.

get_next_elapse() will always fill 'next' with values when it
returns >= 0. Hence, the compiler is wrong about this warning.
Initialize 'next' nevertheless.

first (or second)
Previously the returned object of constructor functions where sometimes
returned as last, sometimes as first and sometimes as second parameter.
Let's clean this up a bit. Here are the new rules:
1. The object the new object is derived from is put first, if there is any
2. The object we are creating will be returned in the next arguments
3. This is followed by any additional arguments
Rationale:
For functions that operate on an object we always put that object first.
Constructors should probably not be too different in this regard. Also,
if the additional parameters might want to use varargs which suggests to
put them last.
Note that this new scheme only applies to constructor functions, not to
all other functions. We do give a lot of freedom for those.
Note that this commit only changes the order of the new functions we
added, for old ones we accept the wrong order and leave it like that.

This was inadvertantly disturbed in e3e0314b when glob support was
added.

architecture support for system calls
Also, turn system call filter bus properties into complex types instead
of concatenated strings.

This may be used in graphical session start-up scripts to upload
environment variables such as $DISPLAY into the systemd manager easily.

- turn strv_merge into strv_extend_strv.
appending strv b to the end of strv a instead of creating a new strv
- strv_append: remove in favor of strv_extend and strv_push.
- strv_remove: write slightly more elegant
- strv_remove_prefix: remove unused function
- strv_overlap: use strv_contains
- strv_printf: STRV_FOREACH handles NULL correctly

Not long ago a failed command would print:
"Failed to start something.service: ..."
regardless of whether the command was to start/stop/restart/etc.
With e3e0314 this was improved to print the method used. E.g. for stopping:
"Failed to StopUnit something.service: ..."
This patch matches the method to a more human readable word. E.g:
"Failed to stop something.service: ..."

We need to properly initialize all error structs before use and free
them after use.
Also, there's no point in flushing stdout if we output a \n anyway...
