MariaDB problem after Proxmox upgrade

[Haeiven]

Hi, ( sorry bad english, i'm french )

I've upgraded my 3.4 proxmox to 4.4, so all my VMs was converted from OpenVz to LXC.

The problem is:

On my LXC container, MariaDB won't launch.

Error:

Best regards,

IIRC I had to install systemd-sysv or install sysvinit and ditch systemd entirely in one or 2 similar cases with mariadb. There is a known compatibility problem regardung lcx and systemd in Jessie. I didn't dig deeper then bacause I lacked time to do that. In one case I installed systemd-sysv from Jessie backports and that solved it.
