12 Contact PLC and get the attributes for this node. Also, if the node model
13 string ends in SKIP_MODEL_STRING, override the hardware requirements
14 configuration value, and skip the checks.
16 Also, update any node network settings at PLC, minus the ip address,
17 so, upload the mac (if node_id was in conf file), gateway, network,
18 broadcast, netmask, dns1/2, and the hostname/domainname.
20 Expect the following keys to be set:
21 BOOT_CD_VERSION A tuple of the current bootcd version
22 SKIP_HARDWARE_REQUIREMENT_CHECK Whether or not we should skip hardware
25 The following keys are set/updated:
26 WAS_NODE_ID_IN_CONF Set to 1 if the node id was in the conf file
27 WAS_NODE_KEY_IN_CONF Set to 1 if the node key was in the conf file
28 BOOT_STATE The current node boot state
29 NODE_MODEL The user specified model of this node
30 NETWORK_SETTINGS A dictionary of the values of the network settings
31 SKIP_HARDWARE_REQUIREMENT_CHECK Whether or not we should skip hardware
34 Return 1 if able to contact PLC and get node info.
35 Raise a BootManagerException if anything fails.
