[systemd-devel] systemd 225: cannot override nspawn service

[crequill]

Hi,

All was running fine with systemd 218.
With nspawn systemd 225, always on archlinux, I've a lot of problems:

1/ I cannot login anymore on containers (/sbin/getatty exist in container):
Failed to get login PTY: No such file or directory

2/ override of nspwawn file seems not to be charged (see my first message):
I've discovered that directory used is now /var/lib/machines (before it was
/var/lib/container). I've corrected in override.conf. With systemd-analyze
dump, I've seen the override file is used but the private network is not up
(I didn't see on host a ve interface).

3/ if I boot one container with: systemd-nspawn -bD
/var/lib/machines/ci-container/ -n, the container boots, the ve interface
is up on host and I have a prompt but netctl cannot see the interface in
container!

[root at ci-container netctl]# systemctl status netctl at host0.service

iproute2 is working:

    inet 192.186.66.10/24 scope global host0
       valid_lft forever preferred_lft forever


Is this a configuration migration problem from systemd 218 to 225?

Best regards
