[gentoo-user] what pgm is rotating my /var/log/syslog, etc. files?

[n952162]

I have two gentoo machines, my primary one and one I cloned off of that.

The original gentoo machine has lots of nice /var/log/syslog.1.gz, etc.
files.

The clone has one big /var/log/syslog file.

I now have logrotate installed in both machines.  I see that the
original has cronie installed and an /etc/cron.daily/logrotate file, but
that corresponding  /etc/logrotate configuration file does not list any
of the important  syslog, kern.log, etc files.

When I do as /etc/cron.daily/logrotate does:

   sudo /usr/bin/logrotate -v /etc/logrotate.conf

I get debug output that shows it does only what /etc/logrotate.conf
tells it to do.  And syslog, etc. are not touched.

Could it be that there's another facility that's doing that work?
