Puppet class inheritance confusion - Server Fault
http://serverfault.com/questions/197909/puppet-class-inheritance-confusion


The difference between import and include statemens is:

import works with files, and does not execute classes
include executes classes
files must be imported before the classes can be included
Note: there is a very strong exception to the last rule: Puppet module lookup. include statement does automatic imports in many situations. Here are some of them:

There are other ways to use inheritance. In Puppet 0.23.1 and higher, it’s possible to add values to resource parameters using the ‘+>’ (‘plusignment’) operator:


class apache {
service { 'apache': require => Package['httpd'] }
}

class apache-ssl inherits apache {
# host certificate is required for SSL to function
Service['apache'] { require +> File['apache.pem'] }


[puppet]
puppet note "::"
The double colon that divides the sections of a class’s name is called the namespace separator.

Installation of RVM in /usr/local/rvm/ is almost complete:

* First you need to add all users that will be using rvm to 'rvm' group,
and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

* To start using RVM you need to run `source /etc/profile.d/rvm.sh`
in all your open shell windows, in rare cases you need to reopen all shell windows.
