systemd System and Service Manager
+CHANGES WITH 208:
+
+ * logind has gained support for facilitating privileged input
+ and drm device access for unprivileged clients. This work is
+ useful to allow Wayland display servers (and similar
+ programs, such as kmscon) to run under the user's ID and
+ access input and drm devices which are normally
+ protected. When this is used (and the kernel is new enough)
+ logind will "mute" IO on the file descriptors passed to
+ Wayland as long as it is in the background and "unmute" it
+ if it returns into the foreground. This allows secure
+ session switching without allowing background sessions to
+ eavesdrop on input and display data. This also introduces
+ session switching support if VT support is turned off in the
+ kernel, and on seats that are not seat0.
+
+ * A new kernel command line option luks.options= is understood
+ now which allows specifiying LUKS options for usage for LUKS
+ encrypted partitions specified with luks.uuid=.
+
+ * tmpfiles.d(5) snippets may now use specifier expansion in
+ path names. More specifically %m, %b, %H, %v, are now
+ replaced by the local machine id, boot id, hostname, and
+ kernel version number.
+
+ * A new tmpfiles.d(5) command "m" has been introduced which
+ may be used to change the owner/group/access mode of a file
+ or directory if it exists, but do nothing if it doesn't.
+
+ * This release removes high-level support for the
+ MemorySoftLimit= cgroup setting. The underlying kernel
+ cgroup attribute memory.soft_limit= is currently badly
+ designed and likely to be removed from the kernel API in its
+ current form, hence we shouldn't expose it for now.
+
+ * The memory.use_hierarchy cgroup attribute is now enabled for
+ all cgroups systemd creates in the memory cgroup
+ hierarchy. This option is likely to be come the built-in
+ default in the kernel anyway, and the non-hierarchial mode
+ never made much sense in the intrinsically hierarchial
+ cgroup system.
+
+ * A new field _SYSTEMD_SLICE= is logged along with all journal
+ messages containing the slice a message was generated
+ from. This is useful to allow easy per-customer filtering of
+ logs among other things.
+
+ * systemd-journald will no longer adjust the group of journal
+ files it creates to the "systemd-journal" group. Instead we
+ rely on the journal directory to be owned by the
+ "systemd-journal" group, and its setgid bit set, so that the
+ kernel file system layer will automatically enforce that
+ journal files inherit this group assignment. The reason for
+ this change is that we cannot allow NSS look-ups from
+ journald which would be necessary to resolve
+ "systemd-journal" to a numeric GID, because this might
+ create deadlocks if NSS involves synchronous queries to
+ other daemons (such as nscd, or sssd) which in turn are
+ logging clients of journald and might block on it, which
+ would then dead lock. A tmpfiles.d(5) snippet included in
+ systemd will make sure the setgid bit and group are
+ properly set on the journal directory if it exists on every
+ boot. However, we recommend adjusting it manually after
+ upgrades too (or from RPM scriptlets), so that the change is
+ not delayed until next reboot.
+
+ * Backlight and random seed files in /var/lib/ have moved into
+ the /var/lib/systemd/ directory, in order to centralize all
+ systemd generated files in one directory.
+
+ * Boot time performance measurements (as displayed by
+ "systemd-analyze" for example) will now read ACPI 5.0 FPDT
+ performance information if that's available to determine how
+ much time BIOS and boot loader initialization required. With
+ a sufficiently new BIOS you hence no longer need to boot
+ with Gummiboot to get access to such information.
