2014-11-21nspawn: Add try-{host,guest} journal link modesMartin Pitt
--link-journal={host,guest} fail if the host does not have persistent journalling enabled and /var/log/journal/ does not exist. Even worse, as there is no stdout/err any more, there is no error message to point that out. Introduce two new modes "try-host" and "try-guest" which don't fail in this case, and instead just silently skip the guest journal setup. Change -j to mean "try-guest" instead of "guest", and fix the wrong --help output for it (it said "host" before). Change systemd-nspawn@.service.in to use "try-guest" so that this unit works with both persistent and non-persistent journals on the host without failing. https://bugs.debian.org/770275
2014-11-05core: introduce new Delegate=yes/no property controlling creation of cgroup ↵Lennart Poettering
subhierarchies For priviliged units this resource control property ensures that the processes have all controllers systemd manages enabled. For unpriviliged services (those with User= set) this ensures that access rights to the service cgroup is granted to the user in question, to create further subgroups. Note that this only applies to the name=systemd hierarchy though, as access to other controllers is not safe for unpriviliged processes. Delegate=yes should be set for container scopes where a systemd instance inside the container shall manage the hierarchies below its own cgroup and have access to all controllers. Delegate=yes should also be set for user@.service, so that systemd --user can run, controlling its own cgroup tree. This commit changes machined, systemd-nspawn@.service and user@.service to set this boolean, in order to ensure that container management will just work, and the user systemd instance can run fine.

THis way we can remove cgroup priviliges after setup, but get them back for the next restart, as we need it.

This causes the container to shut down cleanly when the service is stopped.
