Could you be more specific please?
As I know, when user call sftp client to send files, the server will call pam-systemd.so lib to create session and cgroup.
We can skip call pam-systemd.so by config /etc/pam.d/password-auth drop the line " -session optional pam_systemd.so".
But this config is global, and will affect other services, such as ssh login. We don’t find a way just don’t create cgroup dir for sftp.
@Xiuning Would you please take a look and give some suggestion?
