[chef] RE: Re: Help - Creating a "First Run Only" Resource

["Van Fossan,Randy" < >]

In the examples, are they to go into a resource or a recipe?  I just
don't have enough to build on..

Example from Chef Wiki------
execute "some_command" do
command "command to run once"
notifies :create, "ruby_block[some_command_run_flag]", :immediately
not_if { node.attribute?("some_command_complete") }
end

ruby_block "some_command_run_flag" do
block do
node.set['some_command_complete'] = true
node.save
end
action :nothing
end

What exactly you do not understand ? First boot recipe uses attribute on
node to signal if it was already executed on that node.
