From: Chen Qi <[email protected]>
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.
