Bug #10063: cron resource violates resource ordering
https://projects.puppetlabs.com/issues/10063

Author: Igor .
Status: Unreviewed
Priority: Normal
Assignee: 
Category: cron
Target version: 
Affected Puppet version: 2.7.3
Keywords: cron ordering
Branch: 


Consider the following class
<pre> 
class broken_cron {
        cron { 'myjob':
                command => "/usr/local/sbin/myjob",
                user => root,
                minute => "22"
                hour => "5"
                ensure => present
        }
 
        # Try and cleanup crontab -- this is broken in a rather surprising way!
        
        exec { 'crontab -l|grep -v myjob|crontab -':
                unless => "crontab -l|grep '^# Puppet Name: myjob'",
                path => "/bin:/usr/bin",
                before => Cron['myjob']
                }
 
}
</pre>

if this applied when crontab already contains myjob but with different time 
settings than specified in the cron resource, crontab will end up containing 
the job twice. It seems cron type is prefetching the contents of crontab before 
the exec runs despite the explicit ordering.
