+udev 168
+========
+Bugfixes.
+
+Udev logs a warning now if /run is not writable at udevd
+startup. It will still fall back to /dev/.udev, but this is
+now considered a bug.
+
+The running udev daemon can now cleanly shut down with:
+  udevadm control --exit
+
+Udev in initramfs should clean the state of the udev database
+with: udevadm info --cleanup-db which will remove all state left
+behind from events/rules in initramfs. If initramfs uses
+--cleanup-db and device-mapper/LVM, the rules in initramfs need
+to add OPTIONS+="db_persist" for all dm devices. This will
+prevent removal of the udev database for these devices.
+
+Spawned programs by PROGRAM/IMPORT/RUN now have a hard timeout of
+120 seconds per process. If that timeout is reached the spawned
+process will be killed. The event timeout can be overwritten with
+udev rules.
+
+If systemd is used, udev gets now activated by netlink data.
+Systemd will bind the netlink socket which will buffer all data.
+If needed, such setup allows a seemless update of the udev daemon,
+where no event can be lost during a udevd update/restart.
+Packages need to make sure to: systemctl stop udev.socket udev.service
+or 'mask' udev.service during the upgrade to prevent any unwanted
+auto-spawning of udevd.
+This version of udev conflicts with systemd version below 25. The
+unchanged service files will not wirk correctly.

 The fstab_import callout is no longer built or installed. Udev
 should not be used to mount, does not watch changes to fstab, and
 should not mirror fstab values in the udev database.
