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.

units: use SuccessExitStatus to ignore syntax errors in tmpfiles This makes sense from the point of view of the whole distribution: if there are some specific files that have syntax problems, or unknown users or groups, or use unsupported features, failing the whole service is not useful. In particular, services with tmpfiles --boot should not be started after boot. The premise of --boot is that there are actions which are only safe to do once during boot, because the state evolves later through other means and re-running the boot-time setup would destroy it. If services with --boot fail in the initial transaction, they would be re-run later on when a unit which (indirectly) depends on them is started, causing problems. Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1507501. (If we had a mode where a service would at most run once, and would not be started in subsequent transactions, that'd be a good additional safeguard. Using ExecStart=-... is a bit like that, but it causes all failure to be ignored, which is too big of a hammer.)
