systemd System and Service Manager
+CHANGES WITH 200:
+
+ * The boot-time readahead implementation for rotating media
+ will now read the read-ahead data in multiple passes which
+ consist of all read requests made in equidistant time
+ intervals. This means instead of strictly reading read-ahead
+ data in its physical order on disk we now try to find a
+ middle ground between physical and access time order.
+
+ * /etc/os-release files gained a new BUILD_ID= field for usage
+ on operating systems that provide continuous builds of OS
+ images.

CHANGES WITH 199:
* systemd-python gained an API exposing libsystemd-daemon.
ExecStartPre= may now leave data in /tmp that ExecStart= of
the same service can still access). When a service is
stopped its temporary directories are immediately deleted
- (normal clean-up with tmpfiles still is done in addition to

this though).
* By default, systemd will now set a couple of sysctl
be reasonably safe, and good defaults for all new systems.
* The predictable network naming logic may now be turned off
- with a new kernel command line switch: net.ifnames=0
+ with a new kernel command line switch: net.ifnames=0.
* A new libsystemd-bus module has been added that implements a
pretty complete D-Bus client library. For details see:

* journald will now explicitly flush the journal files to disk
- the latest 5min after each write. This will also mark the
- files as offline then until the next write. This should
- increase reliability. The synchronization delay can be
- configured via SyncIntervalSec= in journald.conf.

* There's a new remote-fs-setup.target unit that can be used
to pull in specific services when at least one remote file
* libudev gained a new call udev_device_set_attribute_value()
to set sysfs attributes of a device.

+ processes executed in parallel based on the number of available
CPUs instead of the amount of available RAM. This is supposed
to provide a more reliable default and limit a too agressive
paralellism for setups with 1000s of devices connected.
