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) 2013-06-15 00:56:39 +04:00			`# This file is part of systemd.`

Rename tmpfiles.d/kmod.conf to static-nodes.conf It is generated using kmod, but apart from that doesn't have much to do with kmod. 2019-08-19 12:05:58 +03:00			`Description=Create list of static device nodes for the current kernel`

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. 2014-07-04 05:07:20 +04:00			`ConditionCapability=CAP_SYS_MODULE`
kmod-static-nodes: don't run if module list is empty With this kmod commit, modules.devname will be empty by default instead of containing just a comment: https://git.kernel.org/cgit/utils/kernel/kmod/kmod.git/commit/?id=4c30a11d5f Refine the startup condition of kmod-static-nodes.service to not run needlessly if the list is empty. 2016-01-11 18:26:17 +03:00			`ConditionFileNotEmpty=/lib/modules/%v/modules.devname`

meson: use jinja2 for unit templates We don't need two (and half) templating systems anymore, yay! I'm keeping the changes minimal, to make the diff manageable. Some enhancements due to a better templating system might be possible in the future. For handling of '## ' — see the next commit. 2021-05-16 12:55:36 +03:00			`ExecStart={{KMOD}} static-nodes --format=tmpfiles --output=/run/tmpfiles.d/static-nodes.conf`
