Many fixes, some additions, and a lot of (experimental) kdbus
work. kdbus is coming along nicely, BTW.
CHANGES WITH 202:
* The output of 'systemctl list-jobs' got some polishing. The
'--type=' argument may now be passed more than once. A new
command 'systemctl list-sockets' has been added which shows
a list of kernel sockets systemd is listening on with the
socket units they belong to, plus the units these socket
* The experimental libsystemd-bus library got substantial
updates to work in conjunction with the (also experimental)
kdbus kernel project. It works well enough to exchange
messages with some sophistication. Note that kdbus is not
ready yet, and the library is mostly an elaborate test case
for now, and not installable.
* systemd gained a new unit 'systemd-static-nodes.service'
that generates static device nodes earlier during boot, and
can run in conjunction with udev.
* libsystemd-login gained a new call sd_pid_get_user_unit()
to retrieve the user systemd unit a process is running
in. This is useful for systems where systemd is used as
* systemd-nspawn now places all containers in the new /machine
top-level cgroup directory in the name=systemd
hierarchy. libvirt will soon do the same, so that we get a
uniform separation of /system, /user and /machine for system
services, user processes and containers/virtual
machines. This new cgroup hierarchy is also useful to stick
stable names to specific container instances, which can be
recognized later this way (this name may be controlled
via systemd-nspawn's new -M switch). libsystemd-login also
gained a new call sd_pid_get_machine_name() to retrieve the
name of the container/VM a specific process belongs to.
* bootchart can now store its data in the journal.
* libsystemd-journal gained a new call
sd_journal_add_conjunction() for AND expressions to the
matching logic. This can be used to express more complex
* journactl can now take multiple --unit= and --user-unit=
* The cryptsetup logic now understands the "luks.key=" kernel
command line switch for specifying a file to read the
decryption key from. Also, if a configured key file is not
found the tool will now automatically fall back to prompting
* Python systemd.journal module was updated to wrap recently
added functions from libsystemd-journal. The interface was
changed to bring the low level interface in s.j._Reader
closer to the C API, and the high level interface in
s.j.Reader was updated to wrap and convert all data about
