If you want the variables to affect all users /etc/profile.d is the way to go.

However, if you want them for a specific user, something like .bashrc makes more sense.

In response to "I don't think there is a reliable method to check if it is all ready there; so it would end up getting added with every run of puppet," there is now a file_line resource available from the puppetlabs stdlib module:

"Ensures that a given line is contained within a file. The implementation matches the full line, including whitespace at the beginning and end. If the line is not contained in the given file, Puppet appends the line to the end of the file to ensure the desired state. Multiple resources can be declared to manage multiple lines in the same file."

Example:

file_line { 'sudo_rule':
  path => '/etc/sudoers',
  line => '%sudo ALL=(ALL) ALL',
}

file_line { 'sudo_rule_nopw':
  path => '/etc/sudoers',
  line => '%sudonopw ALL=(ALL) NOPASSWD: ALL',
}
