Comment 17 for bug 530091

One thing we noticed in debian/registration/node:

# Check if node isn't already registered
. /etc/eucalyptus/eucalyptus.conf
for nip in "$NODES"; do
  if [ "${nip# }" == "${IP}" ]; then
    reglog "Node $IP is already registered."
    exit 1
  fi
done

This code doesn't support /var/lib/eucalyptus/nodes.list, but it seems like it should ...
