systemd-233 in rawhide

[Zbigniew Jędrzejewski-Szmek]

Hi all,

systemd-233 was released yesterday [1], and built today for F26 and rawhide.
There's a bunch of new stuff... including of particular significance
to Fedora:

- we turned "hybrid" cgroups on again. This was tried before,
  unsuccessfully, with /sys/fs/cgroup/systemd using cgroups-v2, and
  /sys/fs/cgroup using cgroups-v1. This time, everything is the same
  as in the "legacy" setup, including /sys/fs/cgroup/systemd using
  cgroups-v1, only /sys/fs/cgroup/unified is using cgroups-v2. This new
  hybrid mode should be compatible with docker and lxc.

  Please test and report issues, in particular if you're using
  containers.  Please note that it's necessary to update systemd in
  the initramfs image for the cgroup hierarchy changes to take effect.

  It is possible to force full unified with
  "systemd.unified_cgroup_hierarchy" on the kernel command line, and
  to disable "hybrid" with
"systemd.legacy_systemd_cgroup_controller".

- systemd-coredump has had its various loose ends tightened, and is
  able to capture more types of crashes and report them better. I'll be
  backporting the bugfixes to F24-25 later on.

- systemd --user instances load environment configuration from /etc/environment,
  /etc/environment.d/*.conf, ~/.config/environment.d/*.conf [2].
  Support for this new feature is in systemd and in gdm sessions, but
  further adjustments are needed to make this work in all session
  types.
