Is that with your patch? If you don't allow kmsg open, maybe systemd
doesn't end up logging for reads either?

That said, the worst part of systemd by far is the insane binary
logging crap, and I would not be surprised if you have scrogged logs.

Quite frankly, everything else in systemd at least has an _excuse_ for
it. The binary logging is a pile of unadulterated shit.
