Comment 2 for bug 490020

It still fails with the most recent version, though with different errors now:

/etc/cron.daily/logrotate:

error: error running non-shared postrotate script for /var/log/denyhosts of '/var/log/denyhosts '
run-parts: /etc/cron.daily/logrotate exited with return code 1

The problem is that /etc/logrotate.d/denyhosts sources /etc/denyhosts.conf which is *not* a valid shell script, because there are space around equal signs of the configuration settings, e.g.:
SECURE_LOG = /var/log/auth.log
