Hi there! I'm exploring possibility to use systemd as process manager / "containizer" for Apache Mesos (http://mesos.apache.org). At the moment I'm trying to use systemctl/systemd-run to implement following: * Start process with specified restrictions (It works wih systemd 211) * Stop process - systemctl stop/ kill works too. * Read process status - systemctl lacks robot readable output of process status. * Reap process status: * there is "systemctl reset-failed" - but it reaps all failed units * services exited with 0 exit code are gone completely (maybe it's not an issue) * Read container (cgroup) resource usage - it is possible to do that manually, but I think it could be great to have an API. * Start processes in --user systemd instance When I call systemd-run --user env I get "Failed to create message: Input/output error", digging with strace shows that dbus starts service "/usr/share/dbus-1/services/org.freedesktop.systemd1.service" which has Exec=/bin/false inside. I'm using Fedora 20 with systemd-211 directly from koji.
I'd appreciate any guides, hints, suggestions. Thanks! ---- Nikita
