I'm very interested in the answer to this question.  I did not realize
there was a hard limit on the amount of logs that journald can support.
I have a project where we need to indefinitely store logs being produced
at a rate of many Mb per day.  A 4Gb limit would definitely be
problematic.

Is there actually a hard limit?  Why?  Can it be circumvented?

Thank you very much for the information.
