command is not run on reboot

[Clint Byrum]

If a system has rebooted, we should run the command again until it succeeds. This will handle the case where ephemeral state such as iptables rules or sysctl settings are asserted by the command.

Change abandoned by Michael Kerrin (<email address hidden>) on branch: master

Reason: Time has moved on. A lot of work and a lot of people need to be on board for this to work.

In the past using o-r-c on reboot seemed the easiest thing to do as we where missing a lot of infrastructure that has since been added. A lot of work will need to be undone to get to using o-r-c on reboot. I could have listed the issues before that o-r-c would solve but can't now.
