  ngcpsp2          - install second node (Pro Edition only)
  ngcpce           - install CE Edition
  ngcpcrole=...    - server role (Carrier)
  ngcpcmaster=...  - IP of master server (Carrier)
  ngcpvers=...     - install specific SP/CE version
  nongcp           - do not install NGCP but install plain Debian only
  noinstall        - do not install neither Debian nor NGCP
  ngcpinst         - force usage of NGCP installer
  ngcpinstvers=... - use specific NGCP installer version
  debianrepo=...   - hostname of Debian APT repository mirror
  sipwiserepo=...  - hostname of Sipwise APT repository mirror

Control target system:

  ngcpnw.dhcp      - use DHCP as network configuration in installed system
  ngcphostname=... - hostname of installed system (defaults to ngcp/sp[1,2])
                     NOTE: do NOT use when installing Pro Edition!
  ngcpeiface=...   - external interface device (defaults to eth0)
  ngcpip1=...      - IP address of first node
  ngcpip2=...      - IP address of second node
  ngcpnetmask=...  - netmask of ha_int interface
  ngcpeaddr=...    - Cluster IP address

The command line options correspond with the available bootoptions.
Command line overrides any present bootoption.

Usage examples:

  # ngcp-deployment ngcpce ngcpnw.dhcp

  # netcardconfig # configure eth0 with static configuration
  # ngcp-deployment ngcppro ngcpsp1
