.TH RAMFS 4
.SH NAME
ramfs \- memory file system
.SH SYNOPSIS
.B ramfs
[
.B -i
]
[
.B -S
.I service
]
.SH DESCRIPTION
.I Ramfs
starts a 9P file server
keeping all files in memory.
Initially the file tree is empty.
.PP
By default
.I ramfs
posts its service as
.B ramfs
using
.IR 9pserve (4).
.PP
The
.B -S
flag specifies an alternate service name for ramfs to use.
.PP
The
.B -i
flag tells
.I ramfs
to use file descriptors 0 and 1 for its communication channel
rather than create a pipe.
This makes it possible to use
.I ramfs
as a file server on a remote machine: the file descriptors 0
and 1 will be the network channel from
.I ramfs
to the client machine.
.PP
This program is useful mainly as an example of how
to write a user-level file server.
It can also be used to provide high-performance temporary files.
