From a3e3b66fbcb18174fc54ffd771ef3a38c9f8defd Mon Sep 17 00:00:00 2001 From: Samuel Mendoza-Jonas Date: Wed, 21 Jan 2015 16:12:14 +1100 Subject: petitboot: Implement ordered boot options Move petitboot to a more familiar 'boot-order' based autoboot system. The discover server now reads multiple values from the petitboot,bootdev parameter and adds them in order to config->autoboot_opts. Boot priority is determined by the options' position in the list. On the client, nc-config now recognises the new boot order, and allows the user to add, remove, and reorder the devices in the list.
