Hi, dbus on centos 7 lxc won't work.
So I'm unable to start or query status units with systemd, for example:
systemctl status Failed to get D-Bus connection: No such file or directory
I have no issues with centos 8 container (debian 10 ones work fine too) This is the output of ps aux on centos 7:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 42712 3860 ? Ss 20:11 0:00 /lib/systemd/systemd systemd.unified_cgroup_hierarchy=1 root 2 0.0 0.0 11840 3052 ? Ss 20:12 0:00 /bin/bash root 28 0.0 0.0 51772 3548 ? R+ 20:19 0:00 ps aux
On Centos 8 instead:

Is there a Centos Bug? Or I missing something? The host is Fedora 32, if you need more information, ask me for. Thanks in advance!
