tmpfiles: create static device nodes before udev is started Since v183, the contents of /usr/lib/udev/devices is no longer copied to /dev on boot, rather systemd-tmpfiles should be used instead. However, as systemd-tmpfiles --create is only ran long after udevd has been started, it is no longer possible to use udev rules to assign permissions to the static nodes. This calls systemd-tmpfiles --create early, before udev is started, and restricts the call to /dev, which is known to be mounted already. In the future, this could also take over the creation of static device nodes from systemd-udevd.

static-nodes: move creation of static nodes from udevd to tmpfiles As of kmod v14, it is possible to export the static node information from /lib/modules/`uname -r`/modules.devname in tmpfiles.d(5) format. Use this functionality to let systemd-tmpfilesd create the static device nodes at boot, and drop the functionality from systemd-udevd. As an effect of this we can move from systemd-udevd to systemd-tmpfiles-setup-dev: * the conditional CAP_MKNOD (replaced by checking if /sys is mounted rw) * ordering before local-fs-pre.target (see 89d09e1b5c65a2d97840f682e0932c8bb499f166)
