All + objects any of the components systemd creates in the cgroup + tree is now suffixed. More specifically, user sessions are + now placed in cgroups suffixed with ".session", users in + cgroups suffixed with ".user", and nspawn containers in + cgroups suffixed with ".nspawn". Furthermore, all cgroup + names are now escaped in a simple scheme to avoid collision + of userspace object names with kernel filenames. This work + is preparation for making these objects relocatable in the + cgroup tree, in order to allow easy resource partitioning of + these objects without causing naming conflicts. + + * systemctl list-dependencies gained the new switches + --plain, --reverse, --after and --before. + + * systemd-inhibit now shows the process name of processes that + have taken an inhibitor lock. + + * nss-myhostname will now also resolve "localhost" + implicitly. This makes /etc/hosts an optional file and + nicely handles that on IPv6 ::1 maps to both "localhost" and + the local hostname. + + * libsystemd-logind.so gained a new call + sd_get_machine_names() to enumerate running containers and + VMs (currently only supported by very new libvirt and + nspawn). sd_login_monitor can now be used to watch + VMs/containers coming and going. + + * .include is not allowed recursively anymore, and only in + unit files. Usually it is better to use drop-in snippets in + .d/*.conf anyway, as introduced with systemd 198. + + * systemd-analyze gained a new "critical-chain" command that + determines the slowest chain of units run during system + boot-up. It is very useful for tracking down where + optimizing boot time is the most beneficial. + + * systemd will no longer allow manipulating service paths in + the name=systemd:/system cgroup tree using ControlGroup= in + units. (But is still fine with it in all other dirs.) + + * There's a new systemd-nspawn@.service service file that may + be used to easily run nspawn containers as system + services. With the container's root directory in + /var/lib/container/foobar it is now sufficient to run + "systemctl start systemd-nspawn@foobar.service" to boot it. + + * systemd-cgls gained a new parameter "--machine" to list only + the processes within a certain container. + + * ConditionSecurity= now can check for "apparmor". We still + are lacking checks for SMACK and IMA for this condition + check though. Patches welcome! + + * A new configuration file /etc/systemd/sleep.conf has been + added that may be used to configure which kernel operation + systemd is supposed to execute when "suspend", "hibernate" + or "hybrid-sleep" is requested. This makes the new kernel + "freeze" state accessible to the user. + + * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape + the passed argument if applicable. + + Contributions from: Auke Kok, Colin Guthrie, Colin Walters, + Cristian Rodríguez, Daniel Buch, Daniel Wallace, Dave Reisner, + Evangelos Foutras, Greg Kroah-Hartman, Harald Hoyer, Josh + Triplett, Kay Sievers, Lennart Poettering, Lukas Nykryn, + MUNEDA Takahiro, Mantas Mikulėnas, Mirco Tischler, Nathaniel + Chen, Nirbheek Chauhan, Ronny Chevalier, Ross Lagerwall, Tom + Gundersen, Umut Tezduyar, Ville Skyttä, Zbigniew + Jędrzejewski-Szmek + CHANGES WITH 202: * The output of 'systemctl list-jobs' got some polishing.
