Bug#1129212: [systemd] printing broken

[Lyndon Brown]

I reported the issue upstream yesterday:
https://github.com/systemd/systemd/issues/40951#issuecomment-3999875630

I spent a bunch of time checking through system logs and digging out
any bits that could possibly be helpful and added this to the upstream
report.

Today they closed it suggesting that it's a downstream Debian issue;
something to do with apparmor blocking access for some reason, and the
problem being "between debian, sups and apparmor".
