Note:
*Missing argument is:
file=wanbootCGI-URL
Specifies the URL of the wanboot-cgi program on the web server
*During the installation, WAN boot refers to the contents of the /etc/netboot hierarchy on the web
server for instructions about how to perform the installation. This directory contains the
configuration information, private key, digital certificate, and certificate authority required for a
WAN boot installation. During the installation, the wanboot-cgi program converts this information
into the WAN boot file system. The wanboot-cgi program then transmits the WAN boot file system
to the client.
