af7fce1cdb install: create_symlink() check unlink() return value
create_symlink() do not check the return value of unlink(), this may
confuse the user.

Before the unlink() call we check the 'force' argument. If it is not set
we fail with -EEXIST, otherwise we unlink() the file, therefore the next
symlink() should not fail with -EEXIST (do not count races...).

However since callers may not have appropriate privileges to unlink()
the file we lose the -EPERM or any other errno code of unlink(), and
return the -EEXIST of the next symlink(). Fix this by checking unlink()
results.

Before:
$ systemctl --force --root=~/container-03 set-default multi-user.target
Failed to set default target: File exists

After:
$ systemctl --force --root=~/container-03 set-default multi-user.target
Failed to set default target: Permission denied

a1484a216e systemctl: allow to change the default target without the --force switch
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  718db96199
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.

9754d56e9b Handle Unix domain socket connections from outside our namespace
NixOS uses Unix domain sockets for certain host <-> container
interaction; i.e. the host connects to a socket visible in the
container's directory tree, where the container uses a .socket unit to
spawn the handler program on demand. This worked in systemd 203, but
in 212 fails with "foo.socket failed to queue service startup job
(Maybe the service file is missing or not a template unit?): No data
available".

The reason is that getpeercred() now returns ENODATA if it can't get
the PID of the client, which happens in this case because the client
is not in the same PID namespace. Since getpeercred() is only used to
generate the instance name, this patch simply handles ENODATA by
creating an instance name "<nr>-unknown".

[zj: reorder clauses and remove (unsigned long) casts.]

d060b62fcb hwdb: PCI - include "primary" model string in subsystem model string
The data in the PCI ids file is randomly inconsistent. Many
subvendor model strings just describe the "product" where the
hardware is built into, not the hardware itself. This causes
some "Network Card Model Foo" to show up as "Laptop Model Bar".

Try to make the best out of this mess and concatenate both
strings to describe the hardware.

2a0abe5b6d bus: process AddMatch/RemoveMatch driver call in proxy
Previously, AddMatch/RemoveMatch calls where processed exclusively in
the proxy. That's racy however, since subscribing to a signal might not
complete before the signal is sent due to some subsequent method call.
Hence, in order to expose the same ordering guarantees as dbus1 process
the AddMatch/RemoveMatch calls from the proxy, so that they are
dispatched synchronously to all following messages, thus fixing the
race.

Ultimately, we should probabably dissolve the driver entirely into the
proxy, as it is purely a compatibility feature anyway...

9ea28c55a2 udev: remove seqnum API and all assumptions about seqnums
The way the kernel namespaces have been implemented breaks assumptions
udev made regarding uevent sequence numbers. Creating devices in a
namespace "steals" uevents and its sequence numbers from the host. It
confuses the "udevadmin settle" logic, which might block until util a
timeout is reached, even when no uevent is pending.

Remove any assumptions about sequence numbers and deprecate libudev's
API exposing these numbers; none of that can reliably be used anymore
when namespaces are involved.

b972115c97 path-util: also check for existence of binary when given absolute path
In contrast to a filename-only argument, find_binary() did not
actually check if an path exists, allowing the code to fail later on.
This was OK, but it seems nicer to treat both paths identically.

Also take advantage of path_make_absolute_cwd doing strdup() by itself
if necessary to simplify.

472fc28fda core: Make sure a stamp file exists for all Persistent=true timers
If a persistent timer has no stamp file yet, it behaves just like a normal
timer until it runs for the first time. If the system is always shut down
while the timer is supposed to run, a stamp file is never created and
Peristent=true has no effect.

This patch fixes this by creating a stamp file with the current time
when the timer is first started.

ca2d378414 Unify GREEDY_REALLOC and GREEDY_REALLOC_T
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.

7cc832b91e networkd: link - require both RUNNING and LOWER_UP before using link
Usually RUNNING implies LOWER_UP, but for drivers that don't support oper state, RUNNING can
also mean that the state is unknown. In that case we should just trust LOWER_UP directly.

ffba61663a networkd: wait for IFF_RUNNING rather than IFF_LOWER_UP
The interface is not fully ready until it enterns RUNNING. This was causing
problems with sending out DHCP messages before the interface was ready, so they
would get lost. In particular this affected DHCP INIT-REBOOT, as it relies on
the first package sent being successful (or it will fall back to a full reboot).

Also improve the logging a lot, to make future debugging of link state a lot
easier.
