Bug 1199488

Description of problem:
If a full system is installed into the container which is run as a service, and then the container shuts down itself, not via stopping the service, it is treated as if the service failed. But simply stopping a machine, no crash or whatever, isn't an error ...

Reading the docs[*] I fail to find/understand if some special action is needed to shut down the container without error.

Note that if the same container is run from the commandline, not as a service, it exits without error and after the last shutdown step "Sending SIGTERM to remaining processes..." systemd-nspawn reports "Container has been shut down."

[*] http://www.freedesktop.org/software/systemd/man/systemd-nspawn.html

Version-Release number of selected component (if applicable):
systemd-208-20.el7.x86_64

How reproducible:
always

Steps to Reproduce:
I'm getting the failure as a part of automated testcase, but the important steps go like this:

1. mkdir -p /var/lib/container/rhel7
2. yum -y --nogpgcheck --installroot /var/lib/container/rhel7 groupinstall minimal
3. ln -s '/usr/lib/systemd/system/systemd-nspawn@.service' '/etc/systemd/system/systemd-nspawn@rhel7'
4. systemctl start systemd-nspawn@rhel7
5. run 'poweroff' in the container
6. systemctl status systemd-nspawn@rhel7

Actual results:
systemd-nspawn - Container rhel7
   Loaded: loaded (/usr/lib/systemd/system/systemd-nspawn@.service; enabled)
   Active: failed (Result: exit-code) since Wed 2015-02-25 20:26:32 CET; 1min 36s ago
