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.

units: conditionalize static device node logic on CAP_SYS_MODULES instead of CAP_MKNOD npsawn containers generally have CAP_MKNOD, since this is required to make PrviateDevices= work. Thus, it's not useful anymore to conditionalize the kmod static device node units. Use CAP_SYS_MODULES instead which is not available for nspawn containers. However, the static device node logic is only done for being able to autoload modules with it, and if we can't do that there's no point in doing it.

units: tmpfiles-setup-dev - allow unsafe file creation to happen in /dev at boot This will allow us to mark static device nodes with '!' to indicate that they should only be created at early boot.
