We simply keep open copies of the dbus connections across the
reexecution and close them as last step of it. A client can thus simply
wait until its connection is dropped to know when the reexecution is
finished.

Instead of the /dev/.run trick we have currently implemented, we decided
to move the early-boot runtime dir to /run.
An existing /var/run directory is bind-mounted to /run. If /var/run is
already a symlink, no action is taken.
An existing /var/lock directory is bind-mounted to /run/lock.
If /var/lock is already a symlink, no action is taken.
To implement the directory vs. symlink logic, we have a:
ConditionPathIsDirectory=
now, which is used in the mount units.
Skipped mount unit in case of symlink:
$ systemctl status var-run.mount
var-run.mount - Runtime Directory
Loaded: loaded (/lib/systemd/system/var-run.mount)
Active: inactive (dead)
start condition failed at Fri, 25 Mar 2011 04:51:41 +0100; 6min ago
Where: /var/run
What: /run
CGroup: name=systemd:/system/var-run.mount
The systemd rpm needs to make sure to add something like:
%pre
mkdir -p -m0755 /run >/dev/null 2>&1 || :
or it needs to be added to filesystem.rpm.
Udev -git already uses /run if that exists, and is writable at bootup.
Otherwise it falls back to the current /dev/.udev.
Dracut and plymouth need to be adopted to switch from /dev/.run to run
too.

Now that we have /dev/.run there's no need to use abstract namespace
sockets. So, let's move things to /dev/.run, to make things more easily
discoverable and improve compat with chroot() and fs namespacing.
The patch adds framework for processing Set requests on properties
and as first consumers allows setting of LogTarget and LogLevel on
interface org.freedesktop.systemd1.Manager of org.freedesktop.systemd1.
The code should be generic enough to allow processing of any
property on other objects and interfaces as well.
No systemctl visible interface is added so far. The LogTarget and
LogLevel are meant for debugging in the first place; user interface
can be added if other usage emerge.
Set on systemwide systemd is restricted to root; I am not sure
how session level access is controlled.
Some unit shall never be start on user request (e.g. shutdown.target)
others never be stopped on user request (e.g. auditd.servce), hence
offer options for both.
