h1. Use UUID's for puppet certnames

Users who wish to deploy their hosts using a random unique id, should enable that setting, and use the certname directive in their puppet.conf     template, e.g.:

    certname = <%25= @host.certname %25>

when the certname was not generated (e.g. for hosts created before enabling this feature) @host.certname would return the host name instead.

for provisioning where DNS is not reliable, it is highly recommended to use certnames.

h1. WARNING

This *does not work well* when you are sharing puppet *storeconfigs* database with Foreman, as Puppet would create a new entry in the db with the UUID as the system name.

the recommended workaround is to dump the db, and not to share puppet and foreman databases.
