#2620 is somehow related to this. While reviewing that, I was wondering if we could/should update existing examples to always use _HOSTNAME= and -m, unifying handling of running and non-running pods. Do you think it is ok or is that not going to work?

_HOSTNAME won't work with the rkt pod UUID if the user started the pod with a custom hostname (--hostname), _MACHINE_ID should work though.

Additionaly, logs can be programatically accessed via the [sd-journal API](https://www.freedesktop.org/software/systemd/man/sd-journal.html).
