The package comes with both an rsyslog and a logrotate configuration file, but rsyslog.logrotate actually only contains a single log file defined by rsyslog.conf:

$ diff -u <(egrep -ho '[/a-z]+/?log/[.a-z]+' rsyslog.conf | sort | uniq) <(egrep -ho '[/a-z]+/?log/[a-z]+(\.log)?' rsyslog.logrotate | sort | uniq) | grep ^\ | cut -c2-
/var/log/messages


Some others that are included for rotation aren't created by rsyslog:

$ diff -u <(egrep -ho '[/a-z]+/?log/[.a-z]+' rsyslog.conf | sort | uniq) <(egrep -ho '[/a-z]+/?log/[a-z]+(\.log)?' rsyslog.logrotate | sort | uniq) | grep ^+/ | cut -c2- | xargs
/var/log/boot.log /var/log/cron /var/log/maillog /var/log/secure /var/log/spooler


And vice versa:

$ diff -u <(egrep -ho '[/a-z]+/?log/[.a-z]+' rsyslog.conf | sort | uniq) <(egrep -ho '[/a-z]+/?log/[a-z]+(\.log)?' rsyslog.logrotate | sort | uniq) | grep ^-/ | cut -c2- | xargs
/var/log/auth.log /var/log/cron.log /var/log/daemon.log /var/log/debug /var/log/kern.log /var/log/lpr.log /var/log/mail.err /var/log/mail.info /var/log/mail.log /var/log/mail.warn /var/log/news /var/log/syslog /var/log/user.log


Please adapt rsyslog.logrotate to include all log files created by the default rsyslog.conf and remove those that aren't.
