error: /etc/logrotate.conf:22 duplicate log entry for /var/log/wtmp

[Tony Travis]

The cron.daily job reports an error running logrotate:

/etc/cron.daily/logrotate:
error: /etc/logrotate.conf:22 duplicate log entry for /var/log/wtmp

There is a duplicate entry for "wtmp" in:
  /etc/logrotate.conf
  /etc/logrotate.d/wtmp

Fix: Comment out the entry in /etc/logrotate.conf
