I was going to look into exactly what's supported by that code and say
something about it. I don't think it supports date-based rotation like log4j
does, which is why I'm not shipping that. It may (or may not) be possible to
just turn off the size based rotation and rely on logrotate, I don't know.
I'm not enough of a Unix person to answer that.
