Description=Create System Users
Documentation=man:sysusers.d(5) man:systemd-sysusers.service(8)
units: reorder/split unit dependency blocks The block is reordered and split to have: 1. description + documentation 2. (optionally) conditions 3. all the dependencies I think it's easier to read the units this way. Also, the Conflicts+Before is seperated out to separate lines. The ordering dependency is "fake", because it could just as well be After=, we are adding it to force ordering wrt. shutdown.target, and it plays a different role than the other Before=, which are about a real ordering on boot.

units: do more reordering of ordering config No functional change, just a cleanup to make the subsequent changes easier to see. This is a continuation of 9810e419425263bde86787bc21251f1ad3c35628 > The block is reordered and split to have: > 1. description + documentation > 2. (optionally) conditions > 3. all the dependencies The dependencies for shutdown.target are listed separately because they are the other deps are for startup, and shutdown.target only matter much later.

After=systemd-remount-fs.service
units: introduce systemd-tmpfiles-setup-dev-early.service This makes tmpfiles, sysusers, and udevd invoked in the following order: 1. systemd-tmpfiles-setup-dev-early.service Create device nodes gracefully, that is, create device nodes anyway by ignoring unknown users and groups. 2. systemd-sysusers.service Create users and groups, to make later invocations of tmpfiles and udevd can resolve necessary users and groups. 3. systemd-tmpfiles-setup-dev.service Adjust owners of previously created device nodes. 4. systemd-udevd.service Process all devices. Especially to make block devices active and can be mountable. 5. systemd-tmpfiles-setup.service Setup basic filesystem. Follow-up for b42482af904ae0b94a6e4501ec595448f0ba1c06. Fixes #28653. Replaces #28681 and #28732.

Before=sysinit.target systemd-update-done.service
units: add ordering dependencies on initrd-switch-root.target For shutdown, we queue shutdown.target/start, so in every unit which should be stopped *before* shutdown, we need both Conflicts and an ordering dependency with shutdown.target (either Before= or After= would work, because stop jobs are always ordered before start jobs). For initrd transition, we queue initrd-switch-root.service/isolate. This automatically creates a /stop job for every running unit without IgnoreOnIsolate. But no ordering dependency is created, unless the unit has a (possibly transitive) ordering dependency on initrd-switch-root.service. Since most units must stop before the transition, we should add the ordering dependency. It is nicer to use Before=initrd-switch-root.target for this. initrd-switch-root.target is ordered before initrd-switch-root.service, so the effect it the same when both are in a transaction. Fixes #23745. To also cover the case where somebody is emergency mode in the initrd and queues initrd-switch-root.service/start (not isolate), also add Conflicts=initrd-switch-root.target, so various units are stopped properly. This extends 2525682565b372b9b83c848bfe89c025fed47a1d to cover all the other services that are touched. It could be consider "operator error", but it's easy to make and it's nicer if we can make this more foolproof.

[Service]
Type=oneshot
RemainAfterExit=yes
units: drop full paths for utilities in $PATH This makes things a bit simpler and the build a bit faster, because we don't have to rewrite files to do the trivial substitution. @rootbindir@ is always in our internal $PATH that we use for non-absolute paths, so there should be no functional change.

ExecStart=systemd-sysusers
units: specify timeouts for more oneshot services Even trivial service occasionally get stuck, for example when there's a problem with the journal. There's nothing more annoying that looking at the cylon eye for a job with an infinite timeout. Use standard 90s for jobs that do some work, and 30s for those which should be almost instantenous.

sysusers: read passwords from the credentials logic Let's make use of our own credentials infrastructure in our tools: let's hook up systemd-sysusers with the credentials logic, so that the root password can be provisioned this way. This is really useful when working with stateless systems, in particular nspawn's "--volatile=yes" switch, as this works now: # systemd-nspawn -i foo.raw --volatile=yes --set-credential=passwd.plaintext-password:foo For the first time we have a nice, non-interactive way to provision the root password for a fully stateless system from the container manager. Yay!

# Optionally, pick up a root password and shell for the root user from a
# credential passed to the service manager. This is useful for importing this
# data from nspawn's --set-credential= switch.
