So, is this the best way to tell if the systemd I am working with supports setting this property on a scope? https://github.com/philips/libcontainer/blob/systemd-default-dependencies-false/cgroups/systemd/apply_systemd.go#L74 Hmm, I figure I am not hipster enough to read this Go code... But yeah, if you check for ReadOnlyProperty when putting together a scope, that sounds like an OK check.

From the docs it seems like it should work: Unless DefaultDependencies=false is used, scope units will implicitly have dependencies of type Conflicts= and Before= on shutdown.target. Well, currenlty not all our props are exposed for transient units yet. Many are, but we were too lazy to add them all. If you need more properties, then let me know, and we can add them. I have added DefaultDependencies= for you now: http://cgit.freedesktop.org/systemd/systemd/commit/?id=261420ba2a20305ad271b6f5f380aa74c5c9dd50 But, in practice: systemd-run --scope --property=DefaultDependencies=false /usr/bin/sleep 5 Unknown assignment DefaultDependencies=false.

[systemd-devel] DefaultDependencies=false on scopes
Hello- How is a user supposed to disable DefaultDependencies on a scope? From the docs it seems like it should work: Unless DefaultDependencies=false is used, scope units will implicitly have dependencies of type Conflicts= and Before= on shutdown.target. But, in practice: systemd-run --scope --property=DefaultDependencies=false /usr/bin/sleep 5 Unknown assignment DefaultDependencies=false. Failed to create message: Invalid argument The root problem I am trying to fix is that it seems the docker daemon uses DefaulDependencies for all of its scopes which means that the containers get killed by systemd before the docker daemon is notified to shutdown. AFAICS, this would need to be added here: http://cgit.freedesktop.org/systemd/systemd/tree/src/libsystemd/sd-bus/bus-util.c#n1319 Thanks, Brandon ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
