2013-06-27core: general cgroup reworkLennart Poettering
Replace the very generic cgroup hookup with a much simpler one. With this change only the high-level cgroup settings remain, the ability to set arbitrary cgroup attributes is removed, so is support for adding units to arbitrary cgroup controllers or setting arbitrary paths for them (especially paths that are different for the various controllers). This also introduces a new -.slice root slice, that is the parent of system.slice and friends. This enables easy admin configuration of root-level cgrouo properties. This replaces DeviceDeny= by DevicePolicy=, and implicitly adds in /dev/null, /dev/zero and friends if DeviceAllow= is used (unless this is turned off by DevicePolicy=).

containers there Containers will now carry a label (normally derived from the root directory name, but configurable by the user), and the container's root cgroup is /machine/<label>. This label is called "machine name", and can cover both containers and VMs (as soon as libvirt also makes use of /machine/). libsystemd-login can be used to query the machine name from a process. This patch also includes numerous clean-ups for the cgroup code.
2013-04-15core: always create /user and /machine top-level cgroup dirsLennart Poettering
This allows clients to put inotify watches on these trees to watch for state changes, without having to wait until these dirs are created. This introduces the new top-level /machine cgroup dir as canonical location where OS containers and VMs shall be located (as discussed with the libvirt folks).

2012-04-12relicense to LGPLv2.1 (with exceptions)Lennart Poettering
We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

This prevents linking of selinux and libdl for another 15 binaries.
