.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
.MR 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.
