Nevertheless, the way *I* would apply extlookup to the problem would
be more like this:
node default {
class { sudoers: }
}
# No additional node definition needed for this purpose
class sudoers { # Not parameterized
# This class should know how to choose
# the default rule set for itself
case $operatingsystem {
"CentOS", "Debian", "Ubuntu", "Solaris":
{ $default_rules = $rules_unixgroup }
default:
{ $default_rules = $rules_other }
}
# If you're using extlookup to get this, then
# it's better to do it right here
$additional_rules = extlookup("additional_sudo_rules")
file { "/tmp/sudoers":
owner => root,
group => root,
mode => 440,
content => template("sudoers/sudoers.erb"),
notify => Exec["check-sudoers"],
}
exec { "check-sudoers":
command => "/usr/sbin/visudo -cf /tmp/sudoers && cp /tmp/
sudoers /etc/sudoers",
refreshonly => true,
}
}
Cheers,
John
