Public bug reported: * I've created a user with adduser --encrypted-home testuser. * when I login via console and logout afterwards with ctrl + d the encrypted Filesystem is still mounted. * if I login again and logout via ctrl + d the encrypted filesystem is succesfully dismounted. * with ssh there is the same behavior but: After logout the first time there is a remaining ssh process of the testuser. I have to kill this process to reproduce the effect. If I don't kill that Process the mount will stay for ever. * This remaining ssh process belongs to the init process: pstree -s 10680 systemd───sshd
