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

["Van Fossan,Randy" < >]

I am still learning to write cookbooks and need to Create a "First Run Only" 
Resource.   I am looking at the Wiki Creating a "First Run Only" Resource
(http://wiki.opscode.com/pages/viewpage.action?pageId=15728818) and am having 
some difficulties interpreting the example.  Does anyone have a cookbook with 
a complete example?

Basically, I have a recipe (config_disk.rb) that needs to do the following 
only once.

------Begin snippet ---
bash "Configure_Disk" do
user "root"
cwd "/tmp"
code <<-EOH
#### Partition sda (Name and Data node)
/sbin/fdisk /dev/sda << EOF
n
p


w
EOF
/sbin/partprobe /dev/sda
#######Partition sdb (Name and Data node)
/sbin/fdisk /dev/sdb << EOF
n
p
1


w
EOF
EOH
end
----End of snippet-----

Thanks
