systemd: fix systemd-udev-hwdb-update serviceChenQi/systemd-udev-hwdb-update
The new version of systemd has implemented the following feature. Opointer.de/blog/projects/stateless.html As a result, the systemd-udev-hwdb-update.service would always run at first boot. This will cause failure if the target device doesn't have enough storage space. Besides, as we run `udevadm hwdb --update' as a postinst of udev-hwdb at rootfs time, there's no need to run this again at system start-up. The purpose of this patch is as follows. If `udev hwdb --update' fails at rootfs time, systemd-udev-hwdb-update.service is executed at first boot; otherwise, the service is not executed. This patch achieves the above goal by setting CondistonNeedsUpdate to "/etc/udev" in the service file, and creating /etc/udev/.updated file if the postinst succeeds.
