WARNING: /etc/chkrootkit.conf is deprecated. Please put your settings in /etc/chkrootkit/chkrootkit.conf instead

I just went through a few hundred messages in root's mail, there were plenty of these: > /etc/cron.daily/chkrootkit: **WARNING**: /etc/chkrootkit.conf is deprecated. Please put your settings in /etc/chkrootkit/chkrootkit.conf instead: /etc/chkrootkit.conf will be ignored in a future release and should be deleted. May I safely delete that obsoleted config file?
