there isnt much of a point in keep maintaining separate kernel configurations for terminal and cpu kernels as the role can be switched with service=cpu boot parameter. to make stuff cosistent, we will just have one "pc" kernel and one "pc64" kernel configuration now.

.SH NAME
|
|
tftpfs \- trivial file transfer protocol (TFTP) file system
|
|
.SH SYNOPSIS

|
|
] [
|

.SH DESCRIPTION
|
|
.I Tftpfs
|
|
serves files from a TFTP server as a filesystem. TFTP
|
|
is mostly used by bootloaders to download kernel images for
|
|
network bootstrap (see
|
|
.IR dhcpd (8)).
|
|
As the protocol has no way of distinguishing files from
|
|
directories, the final path segment needs to conain a dot
|
|
(.) character to be recognized as a file. To access files that
|
|
have no dot in the filename, a trailing dot has to be added
|
|
and will be stripped before it is passed to the server.
|
|
.PP
|
|
The
|
|
.B -D
|
|
option enables 9P debugging messages.
|
|
.PP
|
|
The
|
|
.B -s
|
|
option causes
|
|
.I tftpfs
|
|
to post the 9P service as
|
|
.BI /srv/ srvname
|
|
and disables the default mount.
|
|
.PP
|
|
The default mountpoint
|
|
.BR /n/tftp
|
|
can be changed with the
|
|
.B -B
|
|
.I mtpt
|
|
option.
|
|
.PP
|
|
The
|
|
.B -x
|
|
option specifies an alternate network directory
|
|
.RI ( e.g.,
|
|
.BR /net.alt ).
|
|
.PP
|
|
The ip address of the server can be passed in
|
|
as the last program argument,
|
|
.I ipaddr,
|
|
or in the mount spec (see
|
|
.IR bind (1))
|
|
on a per mount basis.
|
|
.SH EXAMPLE
|
|
Boot a kernel from a tftp server (note the final
|
|
dot in the kernel path).
