# 5-thishost-finalize scripts are called with *this* node's IP, short   #
# hostname and fully qualified hostname.  They are called *after*       #
# 4-restarts (as the numbering system implies).  They are somewhat      #
# esoteric, but can be useful if a local program depends on one of the  #
# things restarted in 4-restarts.                                       #

# NOTE: The name of this script must correspond to the interface name that
#       the context broker knows, not the local interface name which may or
#       may not match.
#
#       The context agent can only handle two NICs at most.  By convention, if
#       there is more than one NIC, the nics need to be labelled "publicnic" or
#       "localnic" as defined by the metadata server.  On EC2, the publicnic
#       is the public IP address that NATs the VM (it does not correspond to
#       an actual NIC in the VM).  Note again that the labelling is NOT the
#       interface name in the VM but rather the labels in the contextualization
#       document where different roles may be played by different IP addresses
#       (and they are labelled with NIC names).
