I don't understand the current situation .So now you get ALL your
volumes activated, or not?

Set systemd.log_level=debug in your command line, and post the exit
from journalctl -b.

That sounds like a problem with the cgroups hierarchy (which uses a
virtual filesystem). I don't remember seeing a problem like that
before.

systemd will not (AFAIK) start your network, and before the 209 or 210
version it needed helper program (NetwokrManager, connman, ip,
ifconfig, etc.) to do it. Now it includes networkd, but you need to
set up .network files (like .service files) to configure it. See [1].

Well, you have a setup that is not, by any means, simple. Also, in my
experience old LVM configurations seem to cause a lot of troubles to
bring to what systemd expects.

John, could you also post here your kernel config? Those cgroups
errors *may* be related to some missing functionality from the kernel.
