========
Bugfixes.
-The udev runtime data moved from /dev/.udev/ to /dev/.run/udev/.
-On systemd systems the tmpfs mountpoint /var/run/ will have a
-permanent "early-boot alias" /dev/.run/, where udev and a couple
-of other early-boot tools will put their runtime data.
+The udev runtime data moved from /dev/.udev/ to /run/udev/. The
+/run mountpoint is supposed to be a tmpfs mounted during early boot,
+available and writable to for all tools at any time during bootup,
+it replaces /var/run/, which should become a symlink some day.
-On systemd systems with LVM used, packagers must make sure, that
-the systemd and initramfs version match. The initramfs needs to
-create the /dev/.run/ mountpoint for udev to store the data, so
-that systemd will not overmount it, which would make the udev
-data from initramfs invisible.
+If /run does not exist, or is not writable, udev will fall back using
+/dev/.udev/.

+On systemd systems with initramfs and LVM used, packagers must
+make sure, that the systemd and initramfs versions match. The initramfs
+needs to create the /run/ mountpoint for udev to store the data, and
+mount this tmpfs to /run in the rootfs, so the that the udev database
+is preserved for the udev version started in the rootfs.
The command 'udevadm info --convert-db' is gone. The udev daemon
itself, at startup, converts any old database version if necessary.
+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.
