[PVE-User] systemd-logind.service

[Kalpesh Sejpal]

Hi,

It's better to enable features Flag nesting=1 for each LXC container with
that error.

Please, check security conserns before changing it.

If you can't do that then another alternative it to mask systemd-logind
service.

Hopefully it can solve the problem.
