Thank you very much!

I'm not sure, if I will debug that, because meanwhile I changed my mind:
I have bpftrace running on the host, while the software in the container
just uses its output. This is done via file system, i.e. a bind mount of
a regular directory.

Anyway, your hint about logging verbosity will be useful for me at some
point, no doubt.

Well, yes. More an OS file system abstraction then :-)
