A recipe to upgrade OmniOS r151006 to r151008 (http://omnios.omniti.com/wiki.php/Upgrade_r151006_r151008)

omnios-upgrade.rb

boot_environment = Mixlib::ShellOut.new("beadm list | grep NR").run_command.stdout

file "/root/boot_environment-before-r151008-upgrade" do
  content boot_environment
end

package "pkg" do
  version "0.5.11,5.11-0.151006:20130731T192303Z"
end

package "web/ca-bundle" do
  version "5.11,5.11-0.151006:20130718T173831Z"
end

package "incorporation/jeos/omnios-userland" do
  version "11,5.11-0.151006"
end

package "runtime/perl/manual" do
  version "5.16.1,5.11-0.151006"
end

execute "pkg update --be-name=omnios-r151008"

If you specify the -H option to beadm list, you can get a semicolon-separated list of fields to make getting the actual boot environment name much easier.
