========
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.
