.Nd boot parameter server
.Sh SYNOPSIS
.Nm rpc.bootparamd
.Op Fl ds
.Op Fl f Ar file
.Op Fl r Ar router
.Sh DESCRIPTION
.Nm
is a server process that provides information to diskless clients
necessary for booting.
It consults the file
.Pa /etc/bootparams .
It should normally be started from
.Pa /etc/rc .
.Pp
This version will allow the use of aliases on the hostname in the
.Pa /etc/bootparams
file.
The hostname returned in response to the booting client's whoami request
will be the name that appears in the config file, not the canonical name.
In this way you can keep the answer short enough
so that machines that cannot handle long hostnames won't fail during boot.
.Pp
While parsing, if a line containing just
.Dq \&+
is found, and the YP subsystem is active, the YP map
.Pa bootparams
will be searched immediately.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl d
Display the debugging information.
The daemon does not fork in this case.
.It Fl f Ar file
Specify the
.Ar file
to read boot parameters from.
Defaults to
.Pa /etc/bootparams .
.It Fl r Ar router
Set the default
.Ar router
(a hostname or IP address).
This defaults to the machine running the server.
.It Fl s
Log the debugging information with syslog.

.Sh BUGS
You may find the syslog loggings too verbose.
.Pp
It's not clear if the non-canonical hack mentioned above is a good idea.
.Sh WARNING
If
.Nm rpc.bootparamd
is run on a system which is also running YP, your YP
domainname will be made public information.
