Rudder

after purge of rudder agent, the entry in crontab still exist:

# dpkg -l rudder-agent && tail -1 /etc/crontab

It leads to cron errors like:

Cron <root@node> if [ ! -e /opt/rudder/etc/disable-agent -a `ps -efww | grep -E "(cf-execd|cf-agent)" | grep -E "/var/rudder/cfengine-community/bin/(cf-execd|cf-agent)" | grep -v grep | wc -l` -eq 0 ]; then /var/rudder/cfengine-community/bin/cf-agent -f failsafe.cf \&\& /var/rudder/cfengine-community/bin/cf-agent; fi (failed)

IMHO, it would be much cleaner to have a file in /etc/crond.d/ instead of an entry in /etc/crontab : its far much easier to change and clean !
