Package bootparamd

A server process which provides boot information to diskless clients

The bootparamd process provides bootparamd, a server process which
provides the information needed by diskless clients in order for them
to successfully boot. Bootparamd looks first in /etc/bootparams for an
entry for that particular client; if a local bootparams file doesn't
exist, it looks at the appropriate Network Information Service (NIS)
map. Some network boot loaders (notably Sun's) rely on special boot
server code on the server, in addition to the RARP and TFTP servers.
This bootparamd server process is compatible with SunOS bootparam clients
and servers which need that boot server code.

You should install bootparamd if you need to provide boot information to
diskless clients on your network.
