Looks like this needs further tweaks. Adding pts/0 to /etc/securetty inside the container made it possible to login via machinectl login. I don't know the security implications of that change, so I've CCed the login maintainers. Maybe the can chime in here if this is something we could ship in the default login /etc/securetty configuration.

Quoting Michael Biebl (bi...@debian.org): Adding pts/0 to /etc/securetty inside the container made it possible to login via machinectl login. I don't know the security implications of that change, so I've CCed the login maintainers. Maybe the can chime in here if this is something we could ship in the default login /etc/securetty configuration. Hello Michael and Mario (and others, eventually), Well, the login maintainers are actually meand I wouldn't even call myself a real maintainer for this key package I'm just one of the last people who still barely look at theh package's bug and check if there are RC bugs. So, well, don't hope too much from me, here, I'm really lacking the proper skills to have a good advice. Still I would happily apply any patch in case more skilled people (who I trust) provide it. signature.asc Description: Digital signature
