Issue #10704 has been updated by Nigel Kersten.

Status changed from Needs Decision to Accepted
Assignee deleted (Nigel Kersten)
Priority changed from Normal to High
Target version set to Telly

I'd like to target this at a version earlier than Telly, but I can't see how we 
could do this without changing behavior significantly.

Am I being too paranoid?

Bug #10704: puppet's idea of /etc/hosts management does not match real world use
https://projects.puppetlabs.com/issues/10704

Author: Bil Tong
Status: Accepted
Priority: High
Assignee: 
Category: host
Target version: Telly
Affected Puppet version: 2.7.6
Keywords: 
Branch: 


Here is a valid extract from an /etc/hosts files on a RHEL box:

    127.0.0.1   localhost localhost.localdomain localhost4 
localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 
localhost6.localdomain6

Here is the code to make puppet add these entries:

        host { 'localhost':
                ip => '127.0.0.1',
                host_aliases => [ 'localhost.localdomain',
                        'localhost4', 'localhost4.localdomain4', ],
        }

       host { 'localhost':
               ip => '::1',
               host_aliases => [ 'localhost.localdomain',
                       'localhost6', 'localhost6.localdomain6', ],
       }

Notice the "localhost" part is the same in both cases. This causes a problem:

    Could not retrieve catalog from remote server: Error 400 on SERVER: 
Duplicate definition: Host[localhost] is already defined in file 
/etc/puppet/modules/networking/manifests/init.pp
