Puppet users - Jun 2013 - Puppet Management with Dual Boot Workstation

Hi everyone, I''m trying to figure out what is the best way to handle a 
single system that dual boots with a puppet client running in each.  In 
this case we are talking about Ubuntu 12.04 and Windows 8.  Should I just 
copy the certificate from one OS to the other?  Should I have a different 
certificate for each OS?  In this case can they have the same hostname, as 
it is the same IP address for both OSes?  Can I somehow use a different 
hostname for each that doesn''t match DNS?  I understand from a client
point
of view it probably doesn''t matter a whole lot, but I am also using
Foreman
(and I imagine Puppet Dashboard would have a similar issue) and I''d
like to
be able to check on the facts and status of both Ubuntu and Windows at any 
given time, not just the OS that happens to be running at the moment.  
Thanks!

Neil

Puppet nodes are usually not identified based on hostname, but rather based 
on certificate name (which is usually the same as hostname). You most 
likely do not want to just copy the certificate over. I just run the 
initial puppet runs with --certname $hostname-$os.$domain to have separate 
certificates for each installation. Also my puppet.conf template has 
certname = <%= @clientcert %> , so that whatever is specified on the 
command line on the first run sticks.

Cheers,
Paul
