What happens with this bug? I have now tried on a fresh Debian Stretch install and my home folder never gets unmounted :(
Not even with the ecryptfs-umount-private.service hack. I'm thinking maybe because "a real logout" is not done? Because if adding a user to new groups, logout/logoin through GDM/lightdm does not update the groups memebership according to command 'id'. Best regards, Stefan.
