Marcus Meissner 28dd57258d Accepting request 176957 from home:fcrozat:branches:Base:System
- Update to release 204:
  + systemd-nspawn creates etc/resolv.conf in container if needed.
  + systemd-nspawn will store metadata about container in container
    cgroup including its root directory.
  + cgroup hierarchy has been reworked, all objects are now suffxed
    (with .session for user sessions, .user for users, .nspawn for
     containers). All cgroup names are now escaped to preven
     collision of object names.
  + systemctl list-dependencies gained --plain, --reverse, --after
    and --before switches.
  + systemd-inhibit shows processes name taking inhibitor lock.
  + nss-myhostname will now resolve "localhost" implicitly.
  + .include is not allowed recursively anymore and only in unit
    files. Drop-in files should be favored in most cases.
  + systemd-analyze gained "critical-chain" command, to get slowest
    chain of units run during boot-up.
  + systemd-nspawn@.service has been added to easily run nspawn
    container for system services. Just start
    "systemd-nspawn@foobar.service" and container from
    /var/lib/container/foobar" will be booted.
  + systemd-cgls has new --machine parameter to list processes from
    one container.
  + ConditionSecurity= can now check for apparmor and SMACK.
  + /etc/systemd/sleep.conf has been introduced to configure which
    kernel operation will be execute when "suspend", "hibernate" or
    "hybrid-sleep" is requrested. It allow new kernel "freeze"
    state to be used too. (This setting won't have any effect if
    pm-utils is installed).
  + ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape
    passed argument if applicable.
